May 20 13:08:23 J-TH kernel: [12436.128067] [drm] GPU HANG: ecode
6:0:0x00000000, in Xorg [993], reason: Hang on render ring, action: reset
May 20 13:08:23 J-TH kernel: [12436.128069] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
May 20 13:08:23 J-TH kernel: [12436.128070] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
May 20 13:08:23 J-TH kernel: [12436.128072] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
May 20 13:08:23 J-TH kernel: [12436.128073] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
May 20 13:08:23 J-TH kernel: [12436.128075] [drm] GPU crash dump saved to
