Stops at "ACPI: power button [PWRF]" when trying to run

I have upgraded from ubuntu 11.04 to 11.10 and after upgrading I am facing the same problem while booting to 11.10 with the latest kernel 3.0.0.12. It stops at:

ACPI: Power Button [PWRF]

I have tried to boot with noapic/acpi=off/nolapic but I am facing the same problem. However, if I boot with the previous kernel then it is working.

Any help in this issue?

I have faced the same issue. Guys can you share your hardware info, maybe we face this problem due to same HW

Here is my hardware info:

We have the same Proc. Btw I have managed to make my new system work. I installed ubuntu upon my old system by upgrading it. And old kernel was left and I am using the old Kernel.

Problem seems to be related with new kernel (branch 3x). please try to use old branch 2x and see if it helps you. Temporary at least. I will inform if will find out the main reason.

Thanks for the comments.

As I had already mentioned in my earlier post that I can boot the system using the old kernel (2.***) but the problem is with the latest kernel (3.***).

In the mean time, I found somewhere that if the USB in the BIOS is disabled then it can boot with the new kernel (3.***). I tried this and it worked. However that is not the solution because then all the USB ports are disabled and no USB device would work. I have an USB mouse and it won't work with the USB in the BIOS being disabled.

Hope that a fix might be available soon.

I've been facing the same problem, except with linux mint and backtrack.
Hardware specs:
core: Intel pentium 4 [HT] 3ghz.
mem: 3gb ddr2
graphics: ati radeon hd 3450 (512 mb)
storage: 80+20 gb

I have the same Mother Board. Intel Dl02GGC2. Trying to boot from USB. It stops at the same place. BIOS only allows 2 settings for ACPI. S1 and S3.
error line is
[0.xxxxxx] ACPI: Power Button [PWRF]

Backtrack5 R1 can not start from usb flash drive.
I've got it to work from the same motherboard as you. Intel Dl02GGC2 pentium 4 3.0 Ghz

I also have 5 other computers I am trying it on.
2 dell dimensions 2400 boot just fine from usb (but slow).
1 2003 abit motherboard. It boots fine if I use a "Plos boot manager" CD.
 The BIOS does not support booting from USB.
1 Dell Vostro 200. It fails booting from the USB if it is set in the BIOS.
  However it boots fine using a "Plos boot manager" CD.
1 ASUS motherboard. It boots fine using it's own bios.

First setting the Intel Dl02GGC2 pentium 4 3.0 Ghz to boot from the bios fails. It gives a "Boot Error" on a black
screen the same as the Vostro 200.

I set the computer to boot from the CD first, the USB second and then the hard disk.
(The BIOS seems to forget the usb flash drive if you pull it out between boots. Why?)
So, I downloaded the "Plos boot manager" iso and burned it to a boot CD.
With this the computer boots dependably first to the Plos boot screen.
There is a boot list to choose from.
Plos has it's own CD and USB driver's so it is not depending on the computers bios.
Next choose the usb to boot from. Up comes the Syslinuz 3.83.... boot:
good. press enter. Next comes the Backtrack menu.
I got this far weeks ago.
oh, oh! If you continue it always fails with this Intel Dl02GGC2 motherboard.
Usually with [x.xxxxxx] ACPI: Power Button [PWRF], but also with ? show=dormant + 0x6/0x50
also the keyboard can lock with the lights flashing. Also it can reboot and
get stuck in the initial BIOS screen.

so now the fix.
-Boot up the usb flash drive on another computer. In the Ubuntu site it says to add
"acpi=off" to /boot/grub/menu.lst. Backtrack does not have that file.
Add it anyway with that one line. It seems to be necessary.
Put the usb back in the Intel computer and also the "Plos boot manager" CD and boot.
In the Plos menu choose usb and press enter.
Up comes the Syslinuz 3.83.... boot: Press enter.
the backtrack menu comes up. Press TAB. Underneath the backtrack menu is a boot options
string. add to it <space> acpi=off. Press enter. Now it often (sometimes) boots successfully.
When it boots successfully the wireless adapters seem to work.
Unfortunately the "system monitor" indicates only 1 CPU.
When you shut down you get a screen with the last line saying "system halted".
Because acpi is disabled you have to press the power button to finish shutting down.
(remember DOS and Windows 3.1)

I put a lot of time getting this far. I hope someone takes this further.

PS Just tried with another Flash usb. It is failing at a different point.
"Loading casper/initrd.gz.............................................................."
now failing a "Loading casper/vmlinuz............................................."
too late to do any more.

i tried what you did Stephen, it doesn't seem to work. when i don't use acpi=off, i get the the same error as you. although when i tried it with that, i just get a blank screen.

Hi all,

I am a newbie here onto Linux.

Was facing same problem as being discussed and system was halting at ACPI [PWRF] for all kernels 3.x till 3.2. acpi=off also did not help to boot the system. (Ubuntu 11.10, same problem i faced on 11.04 also so upgraded but to no use).

With the board D102GGC2 i updated my BIOS first, then tried with boot option idle=poll and idle=halt, separately. Bothe times machine could boot safely.

But now i m not sure wat effect this option has on the system hardware as well as software. Hence i want to request sonmmeone to guide me whether using system with this option is safe or not.

Regards

I had the same/similar problem.

Setting acpi=off let me boot, but my computer wouldn't go to sleep or shut down properly (I had to shut it off manually using the power button after the shut down process completed.)

Setting idle=poll also worked, but according to kernel.org, idle=poll will "will use a lot of power and make the system run hot" [http://www.kernel.org/doc/Documentation/kernel-parameters.txt].

I had sporadic problems shutting down my computer using idle=halt, sometimes it would just hang, other times it shut down properly.

After some more digging around I found a website [http://marc.info/?l=linux-acpi&m=133002974918284&w=2] which suggested this:
    processor.nocst=1

So far, so good.

If you've got a single-processor system, according to the same website maxcpus=1 should work as well.

A Linux newbie faced a recurring system halt issue at the ACPI [PWRF] stage when trying to use kernels 3.x to 3.2, despite attempting the "acpi=off" boot option. After updating their BIOS and trying boot options "idle=poll" and "idle=halt," the system could boot successfully. The user is now seeking guidance on the safety and potential effects of using these options on both hardware and software. Additionally, they are interested in any related blogs or websites that can provide more information on this topic. https://generatorfirst.com/reviews/
