One more,
Note that there seem to be quite different reports, from a recursive fault
to some threads getting marked as "runaway".
I can reproduce the issue now easily, but its proprietary software I cant
reach around.
Understood. Will try to read something from the traces.
This is a regression over 3.0 now, correct?
No, can't say that. I had various recurring issues with 4.9, 4.14 and 4.19
kernels,
aswell as 3.0 and and 3.1.
It's hard to narrow down and often just vanished after a while, and my only
gut-feeling is that condition variables are involved.
I also have a couple cobalt threads *not* pinned to a single cpu.
I'm only talking about the crash during debug - one issue after the other.

Atleast I can now say it’s a single app causing the issue, not using rtnet or
having additional cobalt applications running.
Since I can easily reproduce the issue, I will now try using debian's gcc-8, to
rule out troubles with the toolchain.
Norbert.
