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

It's more likely that the replay is not matching the record, or
there's a similar reason why the replay is not proceeding.
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.
