Are you guys using the realtime profiles from Tuned? Edit /etc/tuned/realtime-virtual-host-variables.conf, Then run tuned-adm profile realtime-virtual-host Note this will perform steps to isolate the configured CPU's, including unpinning all IRQs from the isolated CPUs, (which you can fix after applying the profile). enabling nohz_full=, rcu_nocbs=, etc (can check /usr/lib/tuned/realtime-virtual-host/tuned.conf and script.sh to see what what it (and its parent profiles) do).
I will give this a try, thanks! Peter Wallace Mesa Electronics
