Description Denis Scherbakov 2009-01-22 04:37:56 UTC
Latest working kernel version: 2.6.27.x
Earliest failing kernel version: 2.6.28-rc8, 2.6.28-rc9, 2.6.28, 2.6.28.1
Distribution: Gentoo Linux, but clean 2.6.28  from kernel.org also tested.
Hardware Environment: Dell OptiPlex 960, Intel Core 2 Quad Q9550
Software Environment: Grub Boot Loader

Problem Description: I cannot boot into 2.6.28.x kernels. It stucks right after the beginning:

===================
  Booting 'Gentoo Linux Devel'

kernel /boot/vmlinuz-2.6.28-gentoo-r1 root=/dev/sda3
   [Linux-bzImage, setup=0x2a00, size=0x293070]


Decompressing Linux... Parsing ELF... done.
Booting the kernel.
===================

After that keyboard stops working and I have to do hard poweroff. I tried to boot the kernel in question under qemu. It boots there.

Steps to reproduce: Not sure. I think it is possible only on optiplex 960 hardware.

Comment 2 Thomas Gleixner 2009-01-22 15:18:18 UTC
Can you please boot with:

 earlyprintk=vga

or preferrably (if you can log the output on a second machine via serial)

 earlyprintk=serial,ttyS0,115200

on the kernel command line. That might give us some more info.

Thanks,

Yes, looks like the same issue. Any chance that you apply the patches
from the thread and retest on your machine ? Also please download
http://groups.google.com/group/linux.kernel/attach/008ceeb17b7ea00d/cpuid.c?part=2
compile and run it and stick the output into to bugzilla.

Thanks,

Comment 9 H. Peter Anvin 2009-01-27 16:14:28 UTC
All the patches should now be in tip:master (not yet in Linus' kernel, though), so you can simply test that out.

Comment 12 Denis Scherbakov 2009-02-02 02:40:18 UTC
I applied these two patches and kernel booted successfully.

It appeared that I did have "Limit CPUID value" BIOS parameter selected. So the bug was triggered by two factors: limit cpuid and xsave not handling this exceptional state.

Thank you for your help.
Comment 13 Rafael J. Wysocki 2009-02-02 03:53:27 UTC
Are the patches already in mainline?
Comment 14 Denis Scherbakov 2009-02-02 04:10:32 UTC
I am not sure.

Please only close the bug when you are.

Comment 17 H. Peter Anvin 2009-02-02 07:50:38 UTC
Patch #1 is in mainline.
Patch #2 was NAKed, but an equivalent patch is in the pipeline.

Comment 18 Rafael J. Wysocki 2009-02-02 09:01:51 UTC
Please let me know (or close the bug) when the equivalent of #2 is merged.
Comment 19 Ingo Molnar 2009-02-02 10:00:16 UTC
> Please let me know (or close the bug) when the equivalent of #2 is merged.

patch #1 is already enough to fix the regression, and it's upstream. Patch
#2 future-proofs things in that area - but it does not fix any regression 
(the regression is already fixed by #1).
