Note we sometimes also hit the crc mismatch on this test:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3733/fi-cnl-y3/igt@kms_pipe_crc_basic@suspend-read-crc-pipe-c.html

this is bug 103191
Comment 3 Armando Antonio 2018-02-26 17:40:22 UTC
Hello, the following test cases are working correctly on CNL for three weeks, could we close this bug as fixed?

Rising the priority as this issue occurs in BAT.
Comment 24 Lakshmi 2018-09-17 09:30:57 UTC
Priority is set based on feature.
Comment 25 Martin Peres 2018-11-01 16:59:04 UTC
