Mar 01 16:57:27 foobar kernel: [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [876], reason: Hang on rcs0, action: reset
Mar 01 16:57:27 foobar kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Mar 01 16:57:27 foobar kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Mar 01 16:57:27 foobar kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Mar 01 16:57:27 foobar kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
