I'm using this kernel on openSUSE 11.1 too but have a problem, it won't boot until I disable acpi module to be looded at grub menu (acpi=off).

The boot log looks like this:

[    10.361694] acer-wmi : Acer Laptop ACPI-WMI Extras [     10.373790] Kernel Panic - not syncing: stack-protector: kernel stack is corrupted in: 4845ca0e

...bla bla bla

[     10.623049]  [cffffe424] 0xffffe424 <- #at this line, kernel booting stopped.

Notes:

...

uname -r 2.6.30.2-4-default

but has different kernel-source version as in "Kernel:/HEAD/openSUSE_Factory" repository:

ls -l /usr/src/linux lrwxrwxrwx 1 root root 16 2009-07-26 15:51 /usr/src/linux -> linux-2.6.30.2-6

rpm -qa | grep kernel-source kernel-source-2.6.30.2-6.1

My box is Acer Aspire 5620: http://www1.dealtime.co.uk/xPF-Acer-ACER-AS5622WLMI-050

Should I file the bug? Because it happened similar when I tried to install openSUSE 11.2 Milestone 3-Live CD KDE4 on the same machine (stopped booting with the same error boot log, and could not reach GUI even it booted with acpi=off enabled). Or I should do some more workaround? Dont need, there is 2 bug reports open 2 months ago with similar errors:

https://bugzilla.novell.com/show_bug.cgi?id=508571

This problem is due to a BIOS bug.  Acer has said they will provide a new BIOS to fix the issue, so please upgrade.

Or you can blacklist the acer-wmi kernel module, which should solve the issue as well.

thanks,

Thanks Greg, it solved.

I hope the Acer BIOS update will not take any longer to wait :)

Well, ideally we could fix the problem in the kernel driver as well, we shouldn't crash just because the BIOS engineers can't get their act together...

With acer-wmi enabled, it still failed on 2.6.31-rc5-git3-12, but successfully boots well on Linux 2.6.31-rc5-git3-13. Thanks.

Can someone provide the full trace of the oops that happens here?  With that we have a chance to fix the problem.

I'm still confuse (still newbie) how to capture the full trace of the oops when i could not boot to the system with previous kernel (< 2.6.31-rc5-git3-13 and acer-wmi enabled)? Are using digital camera is the answer?
