Bug Blocks:	11808
Attachments:	Kernel with debug info 2.6.28.1 which does not boot .config of a problematic kernel 2.6.28.1 Output of an earlyprintk over serial cable First patch from google pages (MSR) Second patch from google pages (XSAVE) Outputs of a cpuid.c with "Limit CPUID" set and not set under 2.6.27

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,

Should the need arise, I can also debug the kernel over serial, but only after 01.02.2009, when I am back from vacation.

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.

Comment 15 Rafael J. Wysocki 2009-02-02 06:18:25 UTC

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).
