(In reply to Jani Saarinen from comment #7) > CLosing,m as not seen lately, whitelisting for CI. What about https://intel-gfx-ci.01.org/CI/Patchwork_4496/fi-skl-6770hq/igt@kms_pipe_crc_basic@read-crc-pipe-a-frame-sequence.html ?

Created attachment 131119 [details] [review] Reset GPU before running the tests I ran a test on this problematic fi-skl-6770hq machine for 200 times without any issues. So, maybe we have some garbage left from previous tests that we should clean up. The patch proposes a GPU reset before running the tests. Of course, this slows down the test execution time but I think this would be a worthwhile to give it a go and run full BAT testing for few hundred times with this patch enabled.
Mika, any updates on this. was run taken?

Mika, any updates on this?
I'm running tests on CI farm2 with the patch applied.
These are really hard to reproduce. Might be that we just need to wait few times still and close if not reproduced.
Unable to replicate the issue and the issue hasn't surfaced on CI runs either.
