run-log doesn't match results
last test in run.log:
igt/kms_flip/vblank-vs-suspend-interruptible
In dmesg there are multiple:
<3>[ 120.763022] e1000e 0000:00:1f.6 eno1: Detected Hardware Unit Hang:

there is a lot of spamming from
intel_power_well_enable/intel_power_well_disable, then some genuine logs some
e1000e HArdware unit hangs and more
intel_power_well_enable/intel_power_well_disable spamming.</pre>
