Andi,
Since that issue popped up again after your re-run, I've had a closer look.

The test igt@i915_suspend@basic-s2idle-without-i915 seems to be never executed on BAT ADL machines (e.g., adlp-11, adln-1) because of an abort triggered on those machines by igt@kms_pm_rpm@basic-pci-d3-state.  The latter can be found below among possible fixes -- it succeeded, and that explains why
igt@i915_suspend@basic-s2idle-without-i915 was executed this time, and also for my original submission (rev2).

I suspect there must be an issue with adlp-11 machine that results in failures from igt@i915_suspend@basic-s2idle-without-i915.  Unfortunately, that issue is not visible for now because that test is never executed on that machine.

@BUG Filing,
I'm no sure how re-reporting works, but once you have filters updated after my request submitted earlier today for rev2 of this patch, please also re-report results of rev3 (re-run of rev2).

Thanks,
Janusz
