Public bug reported:
Ubuntu 11.04 running on a Fujitsu Lifebook T901 occasionally crashes at
random points in time. The image remains on the screen, but the keyboard
and mouse stop working, the fans turn off, and the hard drive stops
spinning.
I haven't yet been able to guess what the problem is. Some suspicious kernel
messages are:
