Public bug reported:

Binary package hint: xserver-xorg-video-ati

Background: Running Ubuntu Jaunty. Compiz is disabled. Video card is a
ATI Radeon 9550.

What happens: X crashes at seemingly arbitrary times. It has gotten
pretty bad recently, sometimes happening once an hour or every two
hours. Next time it happens, I will try debugging it with gdb, but it
left an interesting trace in Syslog:
