on CI on KBL igt@gem_exec_suspend@basic-s4-devices caused dmesg warning
[ 242.936931] [drm:intel_dp_aux_ch [i915]] *ERROR* dp aux hw did not signal timeout (has irq: 1)!
[ 242.936950] [drm:intel_dp_aux_ch [i915]] *ERROR* dp_aux_ch not done status 0xac1003ff
Last seen 2 months ago and it used to be very easy to trigger. The fact that it got fixed got shadowed by the nvme bug. Closing now.
