dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

This change was made by a bot.

Try mainline v4.2-rc8:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-rc8-unstable/

Nope. Still get that message.

Tried 4.2.0 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-unstable/ - same result.

Tried 4.3-rc1 [1] on an Asus Zenbook trying to escape bug 1492632 and I am now getting this message.

[1]: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-rc1-unstable/

Also getting this error sporadically, only with an external monitor, on the Dell XPS-13 developer edition (ships w/ ubuntu) on either 5.04 with 3.18 kernel or 5.10 beta with 4.2 kernel. Appears to be some kind of buffer overrun triggered by certain intensive tasks.

Getting this error as well on a Dell XPS-13 developer edition (ubuntu 14.04 LTE) with Kernel 4.3.0-rc2 from mainline[1].

Error occurs when I connect an external monitor on DisplayPort with 4k/60hz: Monitor flickers, turns black every five seconds and turns off completely after two or three minutes.

Error message (constantly with dmesg)

[14142.692434] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
...

After changing resolution back to 1920x1080 everything works fine again without any error messages.
Reproducable with stock kernel on ubuntu (3.13.0-37).

I've just started getting this after updating to linux-image-3.19.0-30-generic from linux-image-3.19.0-28-generic.

NUC 5i3RYH connected via the mini-hdmi port to a 720p tv.

100% repeatable for me using Kodi 15.1. If I play a video I get audio, but the video is all black. If I activate the on-screen display items they render fine, but the video content itself is missing. Audio is fine.

Entering and exiting a video I get this each time:

[ 29.275053] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
[ 29.275763] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
[ 29.316539] sound hdaudioC0D0: HDMI: ELD buf size is 0, force 128
[ 29.316579] sound hdaudioC0D0: HDMI: invalid ELD data byte 0

[ 29.363813] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

Always the first six lines, sometimes more of the (SDE!) lines follow. Always one set when playback begins, and another when playback ends.

Further to this, if I disable VAAPI acceleration in Kodi, the video playback works again, but the kernel messages still appear.

Both the black-video and the messages are completely new in 3.19.0-30 - haven't seen either in earlier kernels.

Just saw this new after updating to the 3.19.0-30-generic kernel in vivid.

Have the same problem on NUC5i5RYH connected to monitor via DisplayPort

> Ubuntu Server 14.04.3 LTS (GNU/Linux 3.19.0-30-generic x86_64)

I can verify that I also am getting this error now that I am running 3.19.0-30 on Intel NUC5i7RYH with Iris 6100 graphics.

I don't know what the error means, but definitely getting it. Upon update now my boot screen doesn't properly load and I have to decrypt the disk with nothing on the screen, clear regression from 3.19.0-28, but not sure if it's related.

I have Lenovo Thinkpad L450 with Intel HD Graphics 5500 and I can confirm the issue is present in the mainline kernel 4.3.0-040300rc. I did not have real noticeable issue - I just see the error messages in the log. It can be reproduced by executing xrandr while an external monitor is connected to the laptop. Any time I execute it, it will produce the error messages. Also connecting the external monitor to DP2 (analog VGA) will produce the error messages in dmesg.

When there is only laptop screen on and no external display connected, it looks executing xrandr will not produce the errors.

The problem is present in 3.19.0-30 but it is not present in 3.19.0-15.
I tried also 3.19.0-28, but using this kernel, my external monitor and even my external USB mouse and keyboard did not work.

Affects me too on HP 820 G2 with Xubuntu 15.04 on Kernel 3.19.0-31-generic.

Maybe I don't get it, but: Is the fix only shutting up the kernel messages or is this fixing the cause?

I'm expiriencing this messages on a Lenovo T450 (20BX011GE) running 15.10 with 4.2.0-16-generic kernel. I see this messages wether external monitor is connected or not, although with much higher frequency with external monitor connected (dp via dock).

It seems like this messages is related to random GDM crashes. I tried to reproduce this behaviour, but I've got no clue when this is happening so far. I will try to investigate this further.

Got this error in my dmesg, and gets daily KDM crashes.

Have an Asus X555L with 2 external monitors connected,
each morning when i get back to the computer, the laptop screen dosn't start,
and I have no working window managment => I can use the active window, but can't change active window.

Also, if i activate the wireless-card, I can see the si (software interupt) in top raise to 100%, and then I lose all controll.
And all I found so far is this error message 1836 times in the dmesg-log

I get this error on my new Toshiba P50t-C-104, with kernel 4.3. No monitors attached, just the default laptop screen. I get a black screen after this message on boot. The only way to boot is to use the 'nomodeset' kernel parameter, but that dissables the intel graphics card.

I'm still getting this on 4.2.0-17-generic with a Lenovo W550s. Moreover, [if you read the patch](http://www.spinics.net/lists/intel-gfx/msg78796.html) you'll see it just affects whether it prints the warning, and doesn't correct the underlying problem. Related or not, I'm also seeing the blank-screen symptoms [reported here](https://github.com/NixOS/nixpkgs/issues/9755).

I am getting this as well WITHOUT any external monitors plugged.
4.2.0-17-generic

I was getting similar behavior on arch Linux with 4.2.x

I also get this error prior:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 138780, found 92519)

Also getting this error with my Dell Latitude E7450 with two external displays connected using DP->mDP cables (E-Dock Port Replicator), together with screen freeze. DM restarts automatically after some time, no need to reboot. However all applications are killed then.

I got this issue while connecting Lenovo G70 to an external monitor using HDMI cable. I was able to workaround this by replacing Nvidia proprietary driver with Nouveau.

I'm running an T450s with 2 external DELL monitors, one 24" and a DELL 27", both are connected by Displayport.

After locking the desktop by windows+L key and returning after some time (minutes) the 27" DELL isn't working anymore and i have to reconfigure the whole display settings, the dmesg output bring up the following lines:
…
[19707.593875] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
[19707.594307] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
[19707.595068] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

Running dell latitude E5450 with nVidea card and seeing this - both the error and sometimes when unlocking screen the monitor keeps flashing on and off every 5 seconds until you change the resolution and change it back.
The best way to do this is CTRL+ALT+F6 then CTRL+ALT+F7

I am also seeing the issue where X is not showing the docked monitors (eDP) as active if I:

suspend -> undock -> resume -> suspend dock -> resume

apport is reporting crashes frequently (using the non free Nvidea driver so I assumed this was the issue).

The bit of information I can add is that apparently Windows users are effected by the screen flashing also (in a company so everyone has the same laptop)!

Dell released a BIOS update to fix the flashing, but it didn't help. Just wanted to add this as it may be a firmware issue.

Had it happen today for the first time. Other than Ubuntu updates no changes to the configuration in months so it seems to be a very recent change. The last time I used the dual monitor config was 5 days ago, with no troubles at all. Now the 2nd monitor (4k) goes blank and comes back about every 5 seconds. Tried resetting display resolution (and then back again) and may have helped for now.

This bug also affects me. Well, now it doesn't anymore, because I've downgraded my system kernel.

Device: notebook Dell Inspiron 5548

Operating system: 64-bit XUbuntu Linux 14.04

Processor: Intel Core i7-5500U

Video: dual chip. These are the two display controllers:
- Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display controller 33000000Hz (requires kernel module / device driver "fglrx"); and
- Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 33000000Hz (requires kernel module / device driver "i915").

Problem: the message "[drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!" floods my dmesg, and from time to time my system crashes and my computer powers off. If I 'cat /var/log/kern.log |grep -i i915' i see a huge amount of messages exactly like this one, hence I can only assume that the kernel module i915_bpo is buggy (or these kernels are buggy while they interact with that kernel module). My notebook is subtly powering off from time to time (unrelated with overheat, I'm pretty sure 'coz I've already monitored temperature parameters and also 'coz I'm using a cooling laptop base/pad, besides the fact that my notebook is brand-new: only 1 week old).

Kernels I've tested which have this issue:
- 3.19.0-18-generic
- 3.19.0-23-generic
- 3.19.0-28-generic
- 3.19.0-33-generic
- 4.2.0-18-generic

All of them have the same problem: the kernel module "i915.ko" (in 4.2.0-18-generic) and the kernel module "i915_bpo.ko" (in kernels 3.19.0-??-generic) randomly cause subtle system shutdown (halt / poweroff) in my notebook.

Solution: I downgraded to kernel 3.13.0-36-generic, which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object (module). Full path for this module: /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

Notes:
- "bdw" stands for "Broadwell"
- "bpo", I believe, stands for "backport"

IMO, this bug is pretty serious and is taking a lot of time to get fixed: my notebook could get damaged if it kept subtly powering off several times a day, on an everyday basis, like it was doing because of this bug. Hence, my strong suggestion to those who are experiencing this issue is to downgrade to a stable kernel version (I recommend kernel 3.13.0-36-generic).

If you don't want to downgrade your kernel: become root ('sudo su'), then open '/etc/default/grub' for edition (e.g. 'gedit /etc/default/grub'), then add the 'nomodeset' option to "GRUB_CMDLINE_LINUX_DEFAULT=" (e.g. GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"), then save the file, exit the text editor and, still as root, run the command 'update-grub && telinit 6'. Your GRUB will be updated and your system will be restarted. After that you won't be able to see OpenGL graphics anymore (e.g. Xscreensaver openGL screensavers won't load), but your system will stop subtly powering off.

This issue affect lenovo t450s as well. As result when connected to docking station with two monitors attached (vga and dvi) monitors are not recognized and dmesg flooded with infamous error ([ 743.432704] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!). It doesn't crash the computer but in some cases make displays unrecognizable when undock
|dock.

True @Tom i'm running Ubuntu 15.10 also on a Lenovo T450s (20BX000TGE - BIOS 1.16) and have these issues.

Since upgrading to Kernel 4.2.0-19-generic i can't remember that the screen issue has occured again...both external displays are working as expected.

I only see this issue:

[ 14.334606] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

sometimes after a fresh boot inside dmesg.

I see the same error message when I try the following:

* laptop is in docking station, external monitor is connected
* send laptop to sleep
* undock laptop
* wake laptop up

The error message is present on the terminal, my KDE session is logged out. Nothing useful in .xsession-errors though.
The laptop is a new T450s, running Kubuntu 15.10.

I got this error on my HP Notebook 15-ac131ne (i3-5005U) with Ubuntu Gnome 15.10 freshly installed. Errors show just before login prompt. I can log in to my desktop after that.

[26255.192670] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
[26255.194650] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

[26255.211472] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

When connecting my Lenovo T450s to the dock, the screen gets black after logging in and I have the same error message:
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

This is with Ubuntu 15.10 and Kernel 4.2.0-19.
Updating to 4.4.0-rc4 didn't help. The problem remained.

Downgrading to 3.13 worked though: The error message is gone and the external screen works again.

So I have this issue as well.

X1 carbon 2015 (broadwell) i5 5200U.

For me this happens without any external monitor, the system just crashes/freezes at random.
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

I have tried the following kernels:

4.2.0-18
4.2.5
4.3.3

It would seem as this is an upstream issue, am I correct?

Bug 80896 is closed with fix released (which isn't fixing the issue), but there is another one open on freedesktop bugtracker.

@joakimkoed Yes this seems to be an upstream issue, see (updated) related freedesktop bug above, with no (working) fix released yet.

I can confirm the behaviour with an without connected external monitor (already confirmed for 4.2. 0-16 genirc, can also confirm for 4.3.3-040303-generic).

I'm considering downgrading to 3.13 like others have said.

Is there any downsides to this for new-ish broadwell machines? Stuff thats not working etc.?

Sorry for spam.

I can confirm 3.13 is okay regarding this issue. Not really a good kernel for broadwell laptops, since some FN-keys don't work etc. but it will do for exam tomorrow :)

I see this bug on Ubuntu Gnome 15.10 with standard kernel only (4.2.0-22-generic at time of writing) with intel microcode active from additional drivers. The only freezes I have noticed appear to be connected to a bug in asus_nb_wmi so are unlikey to help in this case.

Hardware : Asus X555LAB laptop with BIOS revision 503 using i5 5200U processor and integrated graphics.

Also experiencing this with 14.04 dell XPS 9350 Intel(R) Core(TM) i7-5500U

I have the same error and random freeze with kernel 3.19.0-42-generic (and other kernels), not with kernel 3.13.

on Dell Inc. Inspiron 5558 with Ubuntu 14.04.3 LTS 64 bits - Bios A07 - Intel® Core™ i5-5200U CPU @ 2.20GHz × 4 - Intel® HD Graphics 5500

I had to give a presentation with my laptop recently which has the same issue of having the second screen randomly turn black and then back on again.

Interestingly the presentation went without a hickup.

The thing that was different, was that I am having the issue when the secondary screen was connected through HDMi ( with a minidisplay to HDMI adaptor).

I wasn't having the issue using a mini display to VGA connector to a projector with a far lower resolution as my secondary screen.

Want to mention that I am hit by this problem too.

HP-ProBook-430-G2 3.19.0-42-generic x86_64

Downgraded to 3.13.0-74 did not work out because hit by another different problem which shows up in 3.13.0-74, ie when wake up from suspend, the display got messed up. The display will not be restored correctly.

Current Kernel 4.4 RC6 is not problem.

Just testet RC7 from mainline, and it seems to be gone here as well. No messages in /var/log/syslog.

Also tested 4.4.0 RC7 and error is gone.

Also on Dell XPS-13, Ubuntu 15.10, kernel 4.2.0-22.

X doesn't start here :(

We now know the problem is in 3.16, 3.19, 4.2 etc. No need to keep reporting that :)

Please check if 4.4RC7 works, thats helps more.

A bit more contex:

 I run lubuntu 5.10 with 4.4.0 RC7 now and it still happens. Quickly reproducable when doing in-home streaming to my lubuntu client. The stream (h264 decoding) crashes quite rapidly, and the typical dmesg output is present.

Tested 4.4.0 RC7 on Thinkpad T450s with i7-5600U. Error is still present like before, the log message is present with and without ext. display connected, although still much higher frequency of log msgs with ext. display connected.

Happening here as well with 4.4.0 RC7

Just testet RC7 again.

I do not get any errors before I put in HDMI cable. Before I got error messages even without cable, now it only happens with cable. So something got better, but just not good enough :)

Can confirm this bug on Macbook12,1 running 4,4rc7 and a single display on a miniDP connector.

I have to revice my comment from January 4th. The error is gone without external display connected with 4.4.0 rc7 for me too, still occuring with ext. display connected. I'm not sure what I was looking at, maybe booted the wrong kernel, stupid me.

Since yesterday 4.4.0 rc8 is released, same behaviour without external display connected, error is gone. I will check rc8 with external display connected later this day when I'm at home.

Also tested Kernel 4.4 RC8 => the same error appears in /var/log/syslog when i connect my laptop to the tv with a hdmi cable.
The error appears only at the moment when i plug the hdmi cable. Then it stops.
Then i change the configuration of the sound to hdmi display port. And the same error occurs at the moment i changed the sound configuration. see dmesg in attachment.

Just tested 4.4.0-040400rc8-generic (4.4.0 RC8).

Still get the [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)! in dmesg output though.

See attached file for my dmesg output after login.

I've just rebooted with kernel 4.4.0-040400rc8 as well and also continue to see the 'interrupt lied' line. The situation has improved though.

Quick summary, just ask if you want more details/logs.

System information: HP EliteBook, Ubuntu 15.10, i7-5600U, Broadwell-U Integrated Graphics (rev 09)

Previously with the stock Ubuntu 15.10 kernel I was unable to attach a second display unless I connected the display before startup / early in the boot process and closed the laptop lid. Attaching a display over displaylink worked fine in that case. Attaching it over VGA limited me to 1024x768 resolution. Setting modelines for higher resolutions through xrandr resulted in an unusable desktop.

Currently with 4.4.0-040400rc8 I'm able to attach my VGA display after the desktop environment is running and use the second screen to extend the desktop. Setting a different modeline still results in an unusable desktop. I haven't had the opportunity to test a displaylink display since installing this kernel.

Thanks for progressing on this issue.

Found something here: https://bugs.freedesktop.org/show_bug.cgi?id=92084

    drm/i915: shut up gen8+ SDE irq dmesg noise, again

Hi, I am also plagued by this very annoying bug.

I am running Ubuntu 16.04

kernel 4.3.0-7-generic #18-Ubuntu SMP Tue Jan 19 15:46:45 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

on a Dell XPS 13 9343

This particular laptop has a mini DisplayPort output which I connected to a DisplayPort MST hub. The DisplayPort outputs from this hub are connected with DP to HDMI cables to 3 full HD monitors.

My dmesg shows lots of: [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

I also see in the kernel log:

The fix has made its way into the v4.5 merge window and has the mainline commit ID:

ccda3a7 2016-01-13 10:48:11 +0200 N Jani Nikula drm/i915: shut up gen8+ SDE irq dmesg noise, again

So is it into 4.5 RC1?

Yes this patch is in the mainline kernel v4.5-rc1-wily. But I think regarding our problem here it does only what it says: shut up the messages. I just tested it, got a

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

at boot time now (related: https://bugzilla.kernel.org/show_bug.cgi?id=95461), while the

[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

are gone. With external monitor connected things getting worse, gdm isn't able to use the monitor correctly and crashes from time to time. Looks like there are now other i915 bugs (maybe regression?) more urgent. Personally I will stick to 4.4 until I've got time to investigate this further with a clean install of ubuntu to eliminate the possibility that I'm looking at completely unrelated issues here.

Quick test with Kernel 4.5 RC1 connected hdmi for a few seconds => the problem seems to be solved. No error anymore and everything is working fine :-).

System information: Dell Inc. Inspiron 5558 with Ubuntu 14.04.3 LTS 64 bits - Bios A07 - Intel® Core™ i5-5200U CPU @ 2.20GHz × 4 - Intel® HD Graphics 5500

I can confirm that for me kernel 4.5 RC1 also seems to have resolved the problem

HP EliteBook folio 1020; GMA 5300; Ubuntu 15.10 x64

I also just tried the 4.5.0-040500rc1-generic kernel.

Minidisplay to hdmi convertor.

If I put my secondary screen on 3840x2160, I notice that after awhile I get the same black screen interval bug again.

Keeping the resolution to the same as my laptop ( 1920x1080 ) seems to be stable so far. No flicker yet.

Lenovo T450s, Ubuntu 15.10 x64

This bug is causing dual monitor problem for me as well. It looks like it was registered a long ago, when can I track if it gets fixed? It is quite annoying that there are two options: either use laptop's display only or use laggy open drivers...

Reproduced in: DELL INSPIRON 5749
NVIDIA GeForce 840M
Kubuntu 15.10 x64

I would appreciate any advice.

Thank you.

Kernel 4.5 RC1 did not fix it for me. It is even worse at times

I have that message with a HP EliteBook 850 G2 and docking station under kernel 3.19.0-49-generic on Xubuntu 14.04. I think it causes an issue with unrecognised external monitor. I have attached the syslog while reproducing via following steps:

0. directly after boot: external display is not recognised even it's connected to connected docking station (USB works fine)
1. disconnect docking station (line 1)
1. connect docking station (line 7)
2. activate external display (line 788)
3. deactivate external display (1407)
4. external display is not recognised again (USB works fine)

Maybe this is helpfull for fixing.

The error messages have gone away with 4.5-RC1 but the issues remain (i.e. display flicker, display won't turn on again after computer has gone to sleep.

I've currently only got this error message in my DMESG:

[ 21.277697] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun

I've got the same bug. It seems solved with kernel 4.5 RC3.

Same problem here on Lenovo T450s with kernel 4.2.0-27.

I've got a ChromeBook that boots with "i915.modeset=1" kernel parameter. I'm just mentioning it for completeness.

For more or the modeset option, see http://unix.stackexchange.com/questions/110573/what-is-i915-modeset-1-for .

I'm not sure, but sometimes you can cheat with your system.

Example:

1.) working with your dual monitor
2.) lock your desktop (windows key and l for example)
3.) you see both external monitors locked
4.) wait sometime and they go to power safe mode
5.) coming back, press a key and see that only one monitor is available...the other one is still in power safe mode
6.) press STRG+ALT and 2 (or 3 or any other number with a terminal assigned)
7.) see a lot of drm:gen8_irq_handler error messages
8.) wait a moment and the other monitor which was/is in power safe mode will power up and showing up the same errors
9.) now yo back to your graphical UI (most of times STRG+ALT + 7)
10.) you might see that both screens are working again in dual mode...

I did this now for a lot of times (because setting the display settings up again sucks)

Hello,

same bug here on a Lenovo T450.
Kernel-Version: 4.2.0-27-generic

I have two Monitors connected over the docking station. Sometimes it happens when I'm working, but mostly after i look my system and the monitors come back from sleep mode.

Please fix it :) ...

Exact same error message in brand new Dell Latitude e5550 (Intel HD 5500), BUT:
1) No external monitors
2) The laptop won't BOOT, execution hangs up.

Both in 4.2.0-27 amd64 and 4.2.0-16 amd64.
After some reboots it will hang up at
"Started Gnome Display Manager"

Booting in recovery mode I find in dmesg:
"snd_hda_intel 0000:00:03:0: failed to add i915 component master (-19)"

Installing 4.5-rc4-wily gives me:
"possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module 915"
and booting it
"error parsing PCC subspaces from PCCT"
boot hangs up again

Installing linux-firmware_1.156 from http://ubuntu-master.mirror.tudos.de/ubuntu/pool/main/l/linux-firmware/ didn't help. The problems seems to be when loading gnome. The execution hangs up after:
fsck from ...
ubuntu: X1/Y1 clean files, X2/Y2 clean blocks ...

It seems strange,
I might coincidentally experience another bug that I am not aware of...

This is a mysterious bug affecting a LOT of machines. As I suggested at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520040, as a temporary workaround I recommend downgrading to kernel "3.13.0-36-generic".

Try it out and see if it is of any help.

You are right, I missed it.
I can confirm that Switching back to 3.13.0-36, and lightdm(ok that might be only me) gave me a working system.
Thank you very much

Not solved for me with kernel 4.5.0-040500rc3-generic
Still happens.

Seeing with the latest 16.04 desktop nightly, amd64, 2015 Macbook Pro.

I have spam as well and some random crashes loading steam. This started after upgrading to this kernel

Linux slim 3.19.0-51-generic #57-Ubuntu SMP Fri Feb 19 14:05:05 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

External monitor connected to mini display port. Lenovo T450s.

Downgrading to 3.19.0-28 seems to fix the issues for me but that kernel has no support for my WiFi card so I'm stuck with using a kernel with a wonky graphics driver.

A new release candidate 4.5-rc6 has been released with the following changes:

Imre Deak (13):
      drm/i915: Add helper to get a display power ref if it was already enabled
      drm/i915: Ensure the HW is powered during display pipe HW readout
      drm/i915/ibx: Ensure the HW is powered during PLL HW readout
      drm/i915: Ensure the HW is powered when disabling VGA
      drm/i915: Ensure the HW is powered during HW access in assert_pipe

      drm/i915/lvds: Ensure the HW is powered during HW state readout
      drm/i915/skl: Ensure HW is powered during DDB HW state readout

Will give it a go as soon as I can

I played a movie on a secondary screen for about 1hour and 40min without a glitch running the 4.5.-rc6
Will try some more tests tonight by doing some more random work.

So I've been using the secondary screen with random activities like watching youtube clips, browsing, moving windows between the secondary screen and the primary..... different workloads etc for at least 2 hours aaaaand

it didn't blank out on me even once!

Using the 4.5.0-040500rc6-generic build from Ubuntu.

Can other people test out the RC6 of the 4.5 kernel and see if this release candidate also fixes your problems?

So did 4.5.0 RC6 fixed it for you guys?

It still reproduces for me even with this kernel

Yes it fixed it for me.
System is NUC5i7RYH using the HDMI port (using linux-image-4.5.0-040500rc6-generic, amd64)
thank you guys

After some longer tests looks like this is still not 100% with RC6 :(

I haven't noticed any issues in my day-to-day work with RC6. Can't say all issues are completely resolved since I haven't done any exhaustive testing but it's a major improvement over RC5.

Hey folks,

there is an BIOS Update for the Lenovo T450s

[Problem fixes]
- Fixed an issue related to system unable to power on due to chipset hang in some specific situation.

Will try this....

Feedback will come

Ok, nothing new

[ 1510.565374] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

Hi,

we recently got our new E7450 Notebooks from Dell and encountered the same Problems.
Main Problem - Displays flickering or turn to black at all.
We use 3 Displays 2x externeal via DP / HDMI 1920x1080 + E7450 build in with 1920x1080.

OS is Ubuntu 14.04LTS with Kernel 4.2.0-30-generic.
I also tested few hours ago the latest Kernel 4.5.0-040500rc7-generic but after a few minutes one Display started to flicker again.

The dmesg messag "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!" occurs in 4.2 but not in 4.5.

There is another dmesg message in 4.5 that seems to be related to the i915 driver:

Thank you in advance

@thoehlig can you check if you lower the resolution to 1280 x 1024 you still have this problem? If i switch my external monitors to that resolution, the flickering is gone.

I will check this, but its not a solution for me and my users to lower the screen resolution to avoid flickering.

Btw. today with Kernel 4.5 i also had flickering but there were no messages in dmesg.

I'm having similar problems on my Dell XPS 13 9343 running 15.10 with 4.5.0-040500rc6-generic.
I've ran 2 FullHD displays daisy-chained to the miniDP of the notebook, both monitors switched to DP 1.2. This lead to flickering. I since then dropped that configuration and run a single display set to DP 1.1 without flickering.
Still there are some problems.
When watching a YouTube video fullscreen and changing the volume the screen freezes. The volume overlay doesn't appear, but the video seems to play along and the PC doesn't react to keypresses.
The only way out is switching to a TTY (Ctrl+Alt+F1) and restarting lightdm.

Also since I've switched from 4.2.0-30-generic to 4.5.0-040500rc6-generic the messages in dmesg disappeared.
Please let me know when you need any more infos from me.

@Gronor Tested 1280x720 on all Displays, same problem.

That is strange. On that resolution I don't get the flicker. But as you said, it's not an option, though would have been a good indicator for people looking into this.

I have a Dell XPS 13 9343 running Ubuntu 15.10 with 4.2.0-16-generic . Every few days my system freezes and I can move the mouse pointer but can't click on anything. Pressing anything on the keyboard has no effect.

I am using the laptop display + an external monitor Dell U2913WM (2560x1080 @60Hz). I see no flicker or anything else on the displays. I only experience the freeze just as Dr4K4n (stefan-dr4k4n) wrote above.

I think the flickering problem only occurs if you use two external monitors with e-port-dock.

"I think the flickering problem only occurs if you use two external monitors with e-port-dock."

In my case, my laptop suddenly powers off. But another bug that happens in it is this: after a while with Xscreensaver running, the screen flickers and remains that way for some 3 extra seconds after I type my password and the screen is unlocked.

Weird thing is that after the screen is unlocked, some 3 seconds later the flickering stops.

I'm still not sure what we're looking at here, especially if the original message this bug deals with has anything to do with the other described buggy behaviour here, which are: random freezes, display flickering, not working external displays etc. I watched the development of the comments in this bug really closely (not at least because of my own interests being affected as well) and there hasn't been any real progress in investigating this issue(s) further. I think this is not least caused by the complexity and variatons of issues regarding graphics.

IMHO this leads to three taks which has to be done:

1. Identifiying distinct issues and filing distinct bug reports while being aware of possible duplicates.

2. If you're affected and feeling confident in providing more information, investigate those distinct issues further and provide proper amounts of logs/traces etc. possbile related to those distinct issues.

3. Pushing those issues to the proper upstream bugtrackes. (For me this is one of the hardest parts, since I'm not sure which parts play a role here, e.g. kernel, display manager etc.) When I look at my own logs (attached) my issue still looks like a kernel problem.

I've tested the 4.5RC7, the origial message is gone, but my external display (connected to DP of my advanced lenovo dock) stays black if the T450s is docked while booting. If I undock after boot and then dock it again, the system freezes totally and syslog is showing some serious kernel issues. The only way to cirumvent this behaviour is to boot undocked and then dock when the system is fully booted. I'm currently using this workaround in my daily work to see if there are other issues. I think I will file a bug report on bugs.freedesktop.org later.

Happens to me on a NUC i7 DP port..... it happens when monitor goes idle power save mode or when i turn off the monitor.

the issue (massive flickering, turning off) is still very much a problem. I'm on dell xps 13 with two dell monitors daisy chained. The second one is getting most of the flickering.

I am facing same issue after once I force shutdown My OS(laptop). And, now I cannot logon.

I have been affected by this bug for a while as well. This is my setup:

Dell E5450 with Ubuntu 14.04.04 LTS with kernel: 4.2.0-34-generic

The laptop is connected to a Dell E-Port Plus Advanced Port Replicator.

The port replicator is connected via two seperate DP -> mDP cables to two monitors of model Dell 27" QHD U2715H.

I get the same annoying error in dmesg but that is the least of my problems. I also get complete crashes where changing TTY is impossible. The entire laptop will also at times reboot, even when not being used. I also get the same problem others have reported where waking up the laptop causes the second screen to go back into power-save mode. I used to have screen flickering in Windows 10 Professional. But i have not seen this behavior in Ubuntu.

I also get this suspicious error in /var/log/syslog

Ubuntu got stuck (I re-booted without dropping to shell), only mouse movement worked. It was a low memory condition and an external display was connected. The system setup was 15.10 Ubuntu 4.2.0-42-generic #49-Ubuntu SMP using NUC5i7RYH.
