2.3.1 is definitely affected by this bug as well, as it also gained the
prio-coupling rework. But you have to have SCALABLE_SCHED enabled.

I got it. It is - as usual - a trivial one-liner:

PS: The maximum priority level has initialised to a wrong value, causing
threads with prio 0 to be placed out of the queue array.
