another bug report:

While the hang happened again while playing a flash video (I'll try if I can
reproduce it somehow), this time I was able to vt switch, and X was killed and
the following additional lines got appended to dmesg:

Trying to restart X didn't work (X crashed), so I had to reboot the machine.
Not sure if this brings any relevations. Anything I could do to provide more
