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 the abs.0 stress test but not as much. That part is not fully fixed yet but might be with the 5.4 kernel. What I was trying to say is, if you're concerned about LinuxCNC crashing after several hundred/thousand runs, then don't bother with it, otherwise if you plan to use it normally, it should be just fine. How important is it that the kernel crashes after 500 or so LinuxCNC fresh instances, or that the buildbot might have some issues here and there? If it is a big concern, then it'd be best to wait for 5.4 and give that a shot.

I don't think that is the question. The existing 4.14.174 kernel package that we have available also crashes. > 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 The approach I have taken with 2.8 is to hand-build a LinuxCNC package for the supplied RTAI kernel, for those that want it. I have built an RTAI-5.3 + Linux-image-4.19.152 package (several times now) but it is no good for my particular machine as my USB Wifi dongle does not seem to work with it. (Despite the RaLink devices being enabled in the config) In fact it seems to not really want to recognise any USB-Wifi dongles (I have quite a collection) The same device _does_ work with the 4.14.174-rtai kernel (from last April) _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
