RTAI 5.3 with 4.19.152? That doesn't make sense, the RTAI 5.3.1 release I made does a check for a 4.19.195 kernel. The 4.19.174 kernel works with the dongle but 4.19.152 does not. 4.19.195 will have whatever fixes 4.19.174 had and then some. The 4.19.195 kernel crashes eventually when you do

I did the abs.0 stress test and it still dies out after about 300+ runs but latency is lower for me without using `isolcpus` at all. The 5.4 kernel may fix the abs issue but I've been busy with work so I don't have time to go through that. RTAI 5.3.1 is stable with LinuxCNC in my opinion.

Hi everyone, It's been awhile since I've worked on RTAI, I pushed a new release that comes with a lot of bug fixes and clean-ups. The Xenomai developers have fixed a lot of issues in IPIPE and Paolo recently added 5.4 kernel support to RTAI SVN. I know there were some issues with the build bot
