Re: Random system freeze
Try the standard repo kernel. The stack trace reads like some™ bug in the scheduler/PDS likely in combination with the scheduler changes that happened for 5.16 that don't account for out of tree schedulers.
Snooping around a bit PDS/prjc wasn't updated yet for 5.16 by the normal/usual dev [1] so someone else[2] made a compat hack which is likely to not be fully stable/tested/understood.

[2]https://gitlab.com/openglfreak/linux-pr … .16.y-prjc
FWIW there was an rcu related bugfix in 5.16.4 if you're lucky that might do the trick: https://cdn.kernel.org/pub/linux/kernel … Log-5.16.4
