I've never seen this before, and have no idea how to reproduce. Was attempting
to open a new Firefox window, with the system under some I/O load (copying a
DVD). Froze up for a bit, then recovered.
Not sure if this is a useful bug report, but couldn't find any other way to
submit the crash dump. I won't object at all if you close it as useless.

May 21 05:31:08 Watt kernel: [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
May 21 05:31:08 Watt kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
May 21 05:31:08 Watt kernel: [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
May 21 05:31:08 Watt kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
