I am running ptp4l an dphc2sys with priority fifo 99 as well as the
stress-ng. Stress-ng load the CPU with 4 threads at 25% of load (the
board has 4 cores). I do not understand why kworkers have priority 20 by
default. I am trying to rise them to 99 for avoid interferences by the
load. Is this correct or I am focusing on useless stuff?

Might it be fixed by disabling the sanity_freq_limit

I think that just hides the underlying issue. I don't see how CPU load
could trigger those warnings. I suspect it's a HW/driver specific
issue. Do you have any details on that?
