I am not sure which case impacts it. Following cases also has this error: igt/kms_flip/flip-vs-dpms-off-vs-modeset igt/kms_flip/flip-vs-dpms-off-vs-modeset-interruptible igt/kms_flip/single-buffer-flip-vs-dpms-off-vs-modeset igt/kms_flip/single-buffer-flip-vs-dpms-off-vs-modeset-interruptible ==Reproduce steps== ---------------------------- 1. Run full igt
igt/kms_flip/bcs-flip-vs-dpms-interruptible also has this issue.
both test cases works well for me on latest -nightly. Could you please try latest -nightly? does it happens only with full run of igt? What output are you using? DP or eDP? Please attach full dmesg with drm.debug=0xe
