That's a little weird, that's the kind of error you would get if you were trying to boot a machine off a network.

The SHA checksum of the image is correct?

Thank you for testing. The lines with "/usr/bin/" are not quite cosmetic, but you should be able to run "latency-test" after rebooting, as long as you did not run any other realtime-application. Can you try this (rebooting and running latency-test only) and report back?

I just patched /etc/init.d/realtime to use the correct path, so it will be corrected in the next version.

Ok, I found it. Looks like refracta breaks linuxcnc (RTAI) - but I have not found what exactly breaks. So in the meantime this is a workaround - you need working internet for this:

Boot from ISO and open a terminal.
$ sudo apt update
$ sudo apt reinstall linuxcnc
$ latency-test

After reinstallation LCNC it works.

After adding "isolcpus = 2.3" to the GRUB PC freezes, only a hard reset will help.

Maybe some of you have read the ongoing debate about CoC & linuxcnc. Some people think they have to play policemen for the good of the others. Well, that's not my point of view. As there is no debate allowed over that topic and these policemen think their management bull***t is without alternative .. well, I think my remaster is not needed any more. I wish these policemen good luck in destroying commumities - they will prevail, without doubt.

So instead of a devuan chimera iso with linuxcnc 2.8.2 my repo will not be available any more. Say thank you to the policemen .. and don't forget: OBEY !
