I had a brief look at panthor, and it seems to me that this reset only ever
happens when the hardware is truely malfunctioning. I.e. it never runs under
"normal" error conditions, right?

In that case, I think it's fine. But I'd still rather print where the error
occurs and about the error / recovery condition. The "Starting GPU reset" one
still doesn't seem overly useful to me.

In general, the reset prints should still hint some additional information that
helps to understand the root cause.
