Output from /sys/class/drm/card0/error
Desktop hung for several seconds until recovering on it's own. Message in dmesg:
[27469.630541] [drm] stuck on render ring
[27469.630549] [drm] stuck on blitter ring
[27469.630561] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[27469.630563] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[27469.630564] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[27469.630565] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[27469.630567] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
