However, since this was on smae run 2 tests 2 machines, I believe it deserves its own bug, since it is a potential regression.
Also, see https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3516/fi-skl-6700hq/igt@kms_psr_sink_crc@psr_basic.html started flip-flopping on the same issue.
This IGT run appear to be the first occurrence: https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4063/fi-kbl-7560u/igt%40kms_psr_sink_crc%40psr_basic.html https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4063/fi-skl-6600u/igt%40kms_psr_sink_crc%40psr_basic.html Note this is on CI_DRM_3513 i.e. so this is probably due to IGT change.
Note the dmesg appear to come when the subtest is exiting: <7>[ 433.630093] [IGT] kms_psr_sink_crc: exiting, ret=0 <4>[ 433.630477] Setting dangerous option enable_psr - tainting kernel <3>[ 433.655111] [drm:intel_pipe_update_start [i915]] *ERROR* Potential atomic update failure on pipe A <7>[ 433.775081] [IGT] kms_setmode: executing
This appear to fix it: https://patchwork.freedesktop.org/series/36000/
Also tested if I should do the same update to the psr_drrs subtest, but that looks green... https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_744/all.html
