In this backtrace the CPU is waking up the main loop (thread 1), but the

I agree. It is more likely that debugging the replay code instead of the
RCU change will lead to the real cause.
This now also impacts the Gitlab-CI :

How do we tackle this? It feels bad that we have such a subtle problem at
the beginning of the freeze period. Shall we revert the RCU patch 'til the
problem is understood?
I'll look at it today; if I can't make heads or tails of it we'll revert it,
yes.
Sorry if I missed it, but did you find out anything? ... the test is still
failing for me, which is somewhat annoying ...
