Not necesscarily new with 5.15 stable but 3 of the 19 rcutorture scenarios
hang with this -rc: TREE04, TREE07, TASKS03.

5.15 has a known stop machine issue where it hangs after 1.5 hours with cpu
hotplug rcutorture testing. Me and tglx are continuing to debug this. The
issue does not show up on anything but 5.15 stable kernels and neither on
mainline.

I will do some more runs to see if TASKS03 hang is a new thing but it could
be related to the existing issues.

thanks,

 - Joel
