Jul 23 11:08:07 BSWM4 kernel: [ 2485.828630] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Jul 23 11:08:07 BSWM4 kernel: [ 2485.828636] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Jul 23 11:08:07 BSWM4 kernel: [ 2485.828640] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Jul 23 11:08:07 BSWM4 kernel: [ 2485.828644] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
