Could you check v5.17-rc1-rt1? Maybe it was introduced in v5.17 cycle.
Will do!
I would possibly be willing to git bisect the issue. But I am a little
bit confused about how to go about that. What repo/tree would I
precisely bisect (I am using the the patch tarballs from
https://cdn.kernel.org/pub/linux/kernel/projects/rt/)?
if it got introduced post v5.17-rc1-rt1 then we could try to bisect it.
Otherwise we would have to trace it. Since the latency spike is huge, it
should be easy to spot.
Will try and see if I get the tracing working afterwards (will take a
while - slow PC) :)
Kind regards,
