Hi Andy! >I am happy to build a new kernel + RTAI deb for the LinuxCNC repo if >you think that 5.3.1 is worth it?
I think that boils down to how important it is that it may crash after several hundred or a few thousand runs. If the abs.0 stress test is enough to steer you away from RTAI then it would be best to wait for the 5.4 kernel support. The 5.4 kernel is no guarantee that it would fix it either but it's another thing to try. LinuxCNC requires some changes to the hal drivers between kernel releases so I'd probably need help adjusting some of the parport/hostmot drivers to 5.4. The patches for LinuxCNC are usually pretty small to support new kernels and I can usually get most of them. I'd also probably expect a few issues with the build bot as it runs quite a lot of tests in excessive loops but these should go pretty unnoticed on a production system. I was able to execute `runtests` several times in the command line without any issue, but the abs.0 stress test still crashes sometimes: #!/usr/bin/env bash source "${HOME}/linuxcnc-dev/scripts/rip-environment" for PASS in $(seq 1 1000); do echo starting pass "${PASS}" realtime start halcmd loadrt threads halcmd loadrt abs halcmd addf abs.0 thread1 halcmd start halcmd show thread halrun -U done Other than that, I have no problems. It's up to you! Alec _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
