Yeah, that sounds to be a false-positive:

	Starting dynamic subtest: perf
	Starting dynamic subtest: perf
	Dmesg	
	<6> [1163.312914] [IGT] i915_selftest: starting dynamic subtest perf
	<5> [1164.217938] Setting dangerous option enable_psr - tainting kernel
	<5> [1164.217989] Setting dangerous option live_selftests - tainting kernel

Which didn't occur on the first run of the bot:

		issues with Broadwell (rev4)

I'll re-send the series with the SOB/Author fix, collecting the A-B
and R-B received during review of rev4.

Thanks!
