Comment 1 David Björkevik 2010-01-26 19:55:57 UTC 
I got the same error. Switching to a non-PAE kernel did not help.
Comment 2 Greg Szyprowski 2010-01-27 20:22:23 UTC 
I try kernel-2.6.31.12-174.2.3.fc12.i686. I got the same error. Trace below:

Screen image of Trace of kernel bug on shutdown 2.6.31.12-174.2.3.f12.i686

Unable to log trace so I attach this screen image of the trace of the kernel bug preventing proper shutdown of the system on 2.6.31.12-174.2.3.f12.i686
Comment 4 SP 2010-01-28 20:30:39 UTC 
How did you manage to log the trace for the kernel bug?  My message log stops before the trace appears on the screen.
Comment 5 Arthur Radley 2010-01-31 14:52:51 UTC 
"Me, too."

Comment 6 gregor 2010-01-31 22:06:51 UTC 
hi, i have the same problem on a client with i686 kernel (2.6.31.12-174.2.3.fc12.i686)

Comment 7 Adrie Taniwidjaja 2010-02-11 08:57:03 UTC 
But if I do a restart (not shutdown) it doesn't happened.
Is there anybody who don't have this problem ? 
Please info the hardware you used !
Comment 8 J.Kratochvil 2010-02-17 23:02:15 UTC 
(In reply to comment #7)
I can confirm this bug on my PC. I got ASUS P5GDCV motherboard with Pentium IV CPU 3.2GHz.

This bug started with kernel version 2.6.31.12-174.2.3.fc12.i686, short time preliminary to noticing this bug first time I changed plymouth theme with updating initrd but I'm not sure it caused the problem.

Actually I got version 2.6.31.12-174.2.19.fc12.i686, and the bug persists (although I didn't change the plymouth theme and didn't update initrd).

Last kernel without this bug was 2.6.31.9-174.fc12.i686.
Comment 9 SP 2010-02-18 18:21:55 UTC 
I have fc12 on two computers.  Only one was affected by this bug in both the previous and the current kernel (2.6.31.12-174.2.19.fc12.i686). So I guess it is related to a hardware conflict.
Cannot capture the trace as logging seems to stop just before the bug trace appears on the screen.  The behaviour (as described in previous posts) is that the trace appears and the machine halts but does not shutdown or power off.  Here is the beginning of the trace as copied manually from the terminal:

kernel bug at kernel/time/clockevents,c.262!/invalid opcode:0000[#1]SMP ...

lshw: 
(I noticed something odd here.  If you scroll down to the boot ext4 mount point for the harddrive, "configuration: created=2008-07-06 12:17:07 filesystem=ext4 label=/boot lastmountpoint=/boot���7�������
��l=�~��2�K��D��D�7��B��~���K�7��n modified=2010-02-18 09:18:57 mount.fstype=ext4 mount.options=rw,seclabel,relatime,barr"
What's with the corrupted code?)

Comment 10 Cesko Voeten 2010-02-19 10:15:43 UTC 
I'm also experiencing this problem on kernel 2.6.31.12-174.2.19.fc12.i686.
Comment 11 antonio montagnani 2010-02-20 14:03:28 UTC 
 2.6.31.12-174.2.22.fc12.i686.PAE is affected too on my system.
My smolt profile is available here :
http://www.smolts.org/client/show/pub_9ef066bf-3e87-409e-b9ad-1591d5b2af80
Comment 12 J.Kratochvil 2010-02-21 14:13:23 UTC 
Kernel 2.6.31.12-174.2.22.fc12.i686 works fine on my PC. This bug seems me to be repaired.
Comment 13 Adrie Taniwidjaja 2010-02-21 14:32:19 UTC 
I don't think so. Upgrade to kernel 2.6.31.12-174.2.22.fc12 only fix some bugs related to ext4 file system.
And I have been check that this error still happened in my computer.
Comment 14 Arthur Radley 2010-02-22 00:15:29 UTC 
Still happening to me with kernel-PAE-2.6.31.12-174.2.22.fc12.i686. Went back to kernel-PAE-2.6.31.9-174.fc12.i686 (again).
Comment 15 Jack Peirce 2010-02-23 17:06:54 UTC 
This is also happening to me on 2.6.31.12-174.2.22.fc12.x86_64 adding 'nolapic' to the kernel boot parameters seems to provide a workaround.
Comment 16 Adrie Taniwidjaja 2010-02-24 01:19:55 UTC 
Yes adding 'nolapic' option to the kernel makes it work.
But the kernel give me this message at booting : 

"BIOS bug, no explicit IRQ entries using default mptables (tell your hw vendor)"

It explained why this bug not happened on certain hardware.
I used Intel D945GCLF2 board with BIOS ver LF9450J.86A.0171.2009.0403.0118.
Is it something wrong on the BIOS or the new kernel use different things regarding the BIOS ?

What is 'nolapic' doing ?
Comment 17 SP 2010-02-24 15:52:48 UTC 
I have been using 2.6.31.12-174.2.22.fc12 for a few days now and it appears that for my particular hardware (see above) it has fixed the bug.  As I mentioned earlier, this only occurred on one of my machines - the others, using the same kernel, were unaffected.
Comment 18 John DeDourek 2010-02-24 17:56:04 UTC 
Still happens with kernel 2.6.31.12-174.2.22.fc12 on a IBM ThinkCentre MT-M 8143-4JU .  The top fifteen entries of the stack trace, down to hrtimer_nanosleep, call the same functions as in the original report.  From there it differs.  I did not check that the hex numbers were the same.
Comment 19 nicofo 2010-02-28 12:41:04 UTC 
Created attachment 396866 [details]
Screenshot of the stack trace

Same bug for me with a kernel 2.6.31.12-174.2.22.fc12.i686.PAE
(happens also with the 2 (3?) previous Fedora kernels).
It happens every time the PC is shut down.

See the screen shot for the trace (the end seems to be slightly different ?)
Comment 20 Cesko Voeten 2010-03-08 05:57:44 UTC 
Fixed in kernel 2.6.32.9-67.fc12.i686 (at least for my computer, that is)

sry, but i can't check it because we replaced this workstation against a faster one, now we have x86_64.

Comment 22 Adrie Taniwidjaja 2010-03-08 13:32:41 UTC 
Yes it fixed with kernel 2.6.32.9-67.fc12.i686 for my hardware configuration also (Intel D945GCLF2).
Does anyone after upgrade the kernel still have the same problem ?
I think there is a major upgrade there because the kernel have been change from 2.6.31 ... to 2.6.32 ......
Comment 23 John DeDourek 2010-03-08 14:05:39 UTC 
Also fixed in kernel 2.6.32.9-67.fc12.i686 for me.
Comment 24 nicofo 2010-03-08 21:56:59 UTC 
Idem, fixed in 2.6.32.9-67.fc12.i686.PAE for me too.
Comment 25 Arthur Radley 2010-03-29 23:03:29 UTC 
Finally, fixed for me with 2.6.32.9-70.fc12.i686.PAE. Thank you.
Comment 26 J.Kratochvil 2010-03-31 20:20:59 UTC 
Works fine with kernel 2.6.32.9-70.fc12.i686, works fine with kernel 2.6.32.10-90.fc12.i686, this bug has never occurred with kernel 2.6.32.* line. It seems be solved.
Comment 27 Lars Gullik Bjønnes 2010-04-20 14:37:20 UTC 
I am seeing the problem with kernel 2.6.33.2-41.fc13.x86_64
Have not tested the nolapic workaround.

Is there a corresponding F13 bug for this?
Comment 28 Bug Zapper 2010-11-04 00:04:18 UTC 
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
