<6> [130.105442] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
<6> [130.105445] Please file a _new_ bug report at https://gitlab.freedesktop.org/drm/intel/issues/new.
<6> [130.105447] Please see https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs for details.
<6> [130.105450] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
<6> [130.105452] The GPU crash dump is required to analyze GPU hangs, so please always attach it.
