Comment 2 Marta Löfstedt 2018-02-07 12:29:46 UTC

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?
