[  666.776090] [drm] GPU HANG: ecode 8:0:0x86dffffd, in Xorg [736], reason: Hang on rcs0, action: reset
[  666.776092] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  666.776092] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  666.776093] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  666.776093] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
