xzipped gpu crash dump

Hi, I'm filing a new gpu crash dump bug, following the instructions found in
the syslog:

Mar 17 14:12:11 c2 kernel: [76945.504719] [drm] stuck on render ring
Mar 17 14:12:11 c2 kernel: [76945.504722] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Mar 17 14:12:11 c2 kernel: [76945.504722] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Mar 17 14:12:11 c2 kernel: [76945.504723] [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
Mar 17 14:12:11 c2 kernel: [76945.504723] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Mar 17 14:12:11 c2 kernel: [76945.504723] [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.

I've attached the gpu crash dump.  This is on ubuntu 14.04.2 on x86-64 with the
following ubuntu package versions:
