[Bug 610631] [NEW] system freezes completely on random occasions, esp. while playing video

[Michal Bojanowski]

Public bug reported:

My Ubuntu Lucid freezes completely at what seems to be random occasions.
Somewhat more likely while playing a video or playing Battle of Wesnoth.
The freeze is total and I have to reboot by holding down the power
button.

A look at the 'kern.log' (attached) suggests it is a kernel bug.

I'm running 
Linux sinkpad 2.6.32-24-generic #38-Ubuntu SMP Mon Jul 5 09:22:14 UTC 2010 i686 GNU/Linux
