Hi,

I'm very pleased to see there's a new message in dmesg saying what to do...
This is what I get when using Google Maps+WebGL in Google Chrome - the display
freezes for a few seconds and usually Chrome detects a WebGL crash.

[  972.880635] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.

against DRI -> DRM/Intel
[  972.880635] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  972.880635] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
