Bumping the priority to high because it has the potential to affect any modeset (acked by Danvet). I will bump it again if necessary.
Need to see with newer than BIOS ICLSFWR1.R00.2352
Not seen lately: last time 1 month, 2 weeks / 1155 runs ago
Closing.
(In reply to Jani Saarinen from comment #4) > Closing. The time it was no seen for is irrelevant without knowing the reproduction rate. Right now, we have one occurrence, in a drmtip run. There has been only 25 runs after this, so it should definitely remain open.
This also passes on shards today, and BIOS also was updated.
(In reply to Jani Saarinen from comment #6) > This also passes on shards today, and BIOS also was updated. Shards is a fair point. But we got at best 200 runs out of them, and it also "passes" on the same machine on the drmtip_ runs... Does not mean it is fixed though! Right now, we could have a bug with a reproduction rate of 1%. It's ok to drop the priority (just did it), but it does not warrant closing it... Please at least evaluate how bad this WARN is, and if it really is not too impactful for our users, then we can ignore the bug again for a couple more month and close it.
