Here is a similar pattern:
dmesg-warn on:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3174/fi-ctg-p8600/igt@kms_pipe_crc_basic@nonblocking-crc-pipe-b.html
and:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3174/fi-ctg-p8600/igt@kms_pipe_crc_basic@nonblocking-crc-pipe-b-frame-sequence.html
then incomplete at:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3174/fi-ctg-p8600/igt@kms_pipe_crc_basic@read-crc-pipe-b.html
This time we also this a WARNING after
