[Bug 2001914] Re: [i915] [drm] GPU HANG: ecode 12:0:00000000

I keep getting this from time to time on a fully updated questing
install on a ThinkPad P14s Gen 5 with a Core Ultra 7 155H CPU.

This seems to be related to this issue in mesa, but not sure if the mesa issue is just a consequence/amplification of this bug:
