This seems to have the same cause as Bug 100215 <https://bugs.freedesktop.org/show_bug.cgi?id=100215>. We also see several intel_dp_aux_ch timeouts in a row, which might be causing the failure to update in a single vblank [ 435.990152] [drm:intel_dp_aux_ch [i915]] dp_aux_ch timeout status 0x7143003f [ 435.990167] [drm:drm_dp_dpcd_access] Too many retries, giving up. First error: -110 Though it is a different CI test, should we mark as duplicated?
Sure, let's do that! *** This bug has been marked as a duplicate of bug 100215 ***
