[22554.021335] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[22554.021335] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[22554.021336] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[22554.021337] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[22554.021337] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
