It looks like the GPU barfed. If you SSH'd in to the machine you'd find
that everything but the display and resources held by the hung X server
would be fine. Were you doing anything particular in your X session when
this happened? There's a good chance this isn't actually a kernel bug
but instead is a DRI client doing something dumb.

P.S. The bzipped kernel image generally won't help in diagnosing the
problem. The most important thing to include in a bug report is the
kernel version and the dmesg output from the failure if available. Folks
will ask later if more is necessary.
