I have noticed GPU hang in dmesg, but saw no other evidence that something could be wrong... video was fine. Could be false alarm?

[39024.697790] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[39024.697791] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[39024.697792] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[39024.697792] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[39024.697793] [drm] GPU crash dump saved to /sys/class/drm/card0/error
