GPU crash dump

I'm getting the following log each time the machine is waking up from
hibernation:

kernel: [drm] stuck on bsd ring
kernel: [drm] GPU HANG: ecode 5:1:0x01000000, reason: Ring hung, action: reset
kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against
DRI -> DRM/Intel
kernel: [drm] drm/i915 developers can then reassign to the right component if
it's not a kernel issue.
kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please
always attach it.
kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
kernel: drm/i915: Resetting chip after gpu hang

It says to send the message here, so there it is.

I'm using debian sid, and I have the following options set in the i915 module:

options i915 lvds_downclock=1 fastboot=1
