Thunderbolt display turns off randomly, and causes hotplug storm

Asked by Sam Hunt

Current system is a gigabyte z77x-up5-th Moherboard with an I7 processor & hd4000 graphics connected to 2 apple thunderbolt displays.

running ubuntu 12.10,
current kernerl is:

Linux desktop 3.7.0-7-generic #15-Ubuntu SMP Sat Dec 15 16:34:25 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

The problem is that after a while, one, or both monitors start to flicker and then turn off. This is associated with a hotplug "storm" in the dmesg output and eventual system freeze.

Other symptoms include intermittent mouse and keyboard USB lag.

The only solution is to unplug the display which works sometimes or to hard reset the system. However even after doing this the hotplug output continues to loop in dmesg.

I have installed the Xorg-edgers repo and tried various kernels and I915 versions to no avail.

Below is the dmesg output, xrandr -v output

Try with the kernel intended for your release, rather than the one from Raring.

Hi,
thanks for your reply, I have changed kernels:

uname -a
Linux desktop 3.7.4-030704-generic #201301211706 SMP Mon Jan 21 22:07:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Unfortunately however the issue remains, and now my mouse and keyboard are both very slow to respond.

Cheers,
Sam

The kernel for Quantal is 3.5, not 3.7

Sam Hunt (zoggels) said : 		#4

Sorry I probably should have clarified,

 I have tried the 3.5 kernel. I also tried the 3.7 build found here:"http://kernel.ubuntu.com/~kernel-ppa/mainline/"

 "v3.7-rc2-quantal/"

I assume this is meant for quantal?

All had the same effect however,

The kernel for Quantal is 3.5, that's why it's the version for it in the repos. If you start using kernels outside the official repis then we cannot guarantee the results

That makes sense, I have reinstalled ubuntu 12.10 however now the system is almost unusable. For some reason in top there is a kworker client using all the cpu.

echo "options drm_kms_helper poll=N" | sudo tee -a /etc/modprobe.d/local.conf

Reboot to test

Can you help with this problem?
