RELEASE 2.8............... As JT mentioned, if/when the rtai problem gets resolved, then release that particular version.

My plan was to offer both preempt-rt and RTAI ISOs for fresh installs with Debian Buster, and packages for both realtime systems for the other supported OSs too. Unfortunately, despite a lot of effort on the part of Alec and a lesser amount by myself we have not managed to make the RTAI system exit cleanly under all circumstances. Specifically a script that starts realtime, loads an instance of the abs component and then exists will cause a kernel lock up after hundreds to thousands of cycles. Unfortunately this means that runtests will frequently crash the buildbot, so is a more serious problem than it might seem. As far as I know the system is reliable and stable while actually running LinuxCNC. There is a similar problem simply loading and unloading the RTAI kernel modules (No LinuxCNC code involved), but that takes tens of thousands of cycles (typically) to show so may be an entirely different issue. Unfortunately many existing users are likely to have machines that won't work acceptably with preempt-rt and, whilst 2.8 does run on 32-bit Wheezy + RTAI I really would like to be offering an upgrade path to a supported OS. So I don't really know what to do. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
