GPU crash dump

Judging from dmesg, I got a GPU hang and I'm expected to file a bug.

against DRI -> DRM/Intel
[  761.375451] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  761.375452] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
