Public bug reported:
Yesterday while my system was not being used, the GPU suddenly crashed,
as indicated by syslog:

Failed to schedule IB !
The last two messages repeat several times per second, inflating the
syslog to a nice 850MB until it was finally rebooted (which required a
hard shutdown, as it appeared to just lock up at a blank screen after
the usual shutdown process).
The last thing I was doing with it was watching video in VLC. Of note is
that I stopped xcompmgr shortly after starting the video as it was
causing a lot of frames to drop (which is unusual as well).
I tried to report this using ubuntu-bug, but only get timeout errors
when submitting it.
