Created attachment 128097 [details] dmesg 1 With the current nightly I can get the below trace in so far two different scenarios. First is while running the BAT suite in which case it happens during the kms_busy/basic-flip-default-C subtest, and I also got it while running test manually while running kms_setmode/basic.
