Comment 2 Francesco Balestrieri 2019-06-18 13:57:52 UTC
From a chat with Chris (incorrectness to be blamed on me paraphrasing):

The test repeatedly resets the GPU and checks that we can execute a request afterwards. The fact that it fails isn't so critical for users, and may even be related to us using a timeout that is too short. However there have been other issues with reset (see https://bugs.freedesktop.org/show_bug.cgi?id=110683) that could be related. Also, in passing runs ICL resets < 100 times, other platforms > 1000.

Set to "high" priority to reflect assessment done by Francesco's team
Comment 4 Francesco Balestrieri 2019-07-30 04:27:21 UTC
So far this has occurred twice in two consecutive runs on icl-y, then not again for a month/68 runs. Let's keep monitoring it to see if it happens again and decide next steps then.
Comment 5 Francesco Balestrieri 2019-08-06 05:07:24 UTC
Not seen im 90 runs / 1 month , 3 weeks. Closing.
