[75195.004067] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[75195.004071] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[75195.004075] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI - DRM/Intel
[75195.004078] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[75195.004082] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
