Thank you, I tried this with v6.19 and PREEMPT_RT and got this during a reboot:

So the time to was is ~120s with PREEMPT_RT and 7s without.
The interesting difference between these two traces is that the second one only
contains messages with "status" d..2. while the first also contains some with different status
(191 of 265126). Could these be the reason for the delay.
