Comment 19 for bug 275359

Hi,

I have a Lenovo T61 and I had a Kernel panic today (frozen X-Server with blinking Capslock-Led). The logs did not show anything about right before the panic.

Now after the reboot I saw this OOps and I think it might be related.

I have installed the backported modules package.
ii linux-backports-modules-2.6.27-7-generic 2.6.27-7.6 Ubuntu supplied Linux modules for version 2.6.27 on x86/x86_64
ii linux-backports-modules-intrepid 2.6.27.7.11 Generic Linux backported drivers.
ii linux-backports-modules-intrepid-generic 2.6.27.7.11 Backported drivers for generic kernel image

uname -a:
Linux bart 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux

This is the kernel messages I observed (I hope this helps):
