Oct 26 00:43:08 4720z kernel: [242523.988101] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Oct 26 00:43:08 4720z kernel: [242523.988106] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Oct 26 00:43:08 4720z kernel: [242523.988110] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Oct 26 00:43:08 4720z kernel: [242523.988115] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
