Usually signaltest generated reproducible results.

I did see those higher numbers also for v5.10-rc1-rt1 (forgot to post
those). For arm64 the max latency was even higher, around 450us. But I
don't have a lot of data so I wouldn't jump to any conclusion.

Yes, Just fired up signaltest 5 times for arm64 and x86_64 with the
latest release. Keep you posted.
