[67426.377790] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [3674], reason: Hang on rcs0, action: reset
[67426.377793] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[67426.377793] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[67426.377794] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[67426.377795] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
