RTAI with 4.19.152 - Bugs Fixed. Testers Needed

RTAI is working with the 4.19.152 kernel, IPIPE release 15.

Latency on AMD Ryzen is staying below 10 microseconds.

The load/unload crash test bug looks fixed.

No Deb packages yet.

I bet you're feeling pretty good, I know this has been a long haul.
Well done.

Well might NOT be over yet. It works fine here but Andy just tried this earlier today and he said:
"I tried running the abs.0 test in a loop with your new RTAI and 4.19.152. Unfortunately the old problem is still there, it locked the machine after 111 iterations. "

This script:

#!/bin/bash
sudo dmesg -c > /dev/null
rm ${HOME}/test-results/*
source ${HOME}/linuxcnc-dev/scripts/rip-environment
for PASS in $(seq 1 1000); do
echo starting pass ${PASS}
runtests ${HOME}/linuxcnc-dev/tests/abs.0
# uncomment these lines to make it crash less often
#DMESG=$(printf "${HOME}/test-results/dmesg.%04d" ${PASS})
#sudo dmesg -c > ${DMESG}
#cat ${DMESG} | cut -d ] -f 2- > ${DMESG}.cut
#sync
done

I saw that a little after I posted.

We need more testers. Somebody else ran it for 10K test cycles on an Intel i5 and it was fine.

Andrew got the boot !
Thanks for reporting it.
