Was there anything done already? Did we increase the timeout? The issue was
seen only once in CI_DRM_5922.

If it is a real issue, not a single time random fluke, it means we may fail to
reset from atomic context from time to time, leading to a wedged GPU if it ever
happens on a live system. But that's a stretch.

TBH, I don't think that this particular issue has anything to do with atomic
contexts. It is just one engine being randomly stuck or taking more time to
reset than expected. So it is not that serious, especially with this failure
rate.

Let's keep an eye on this.
