Thanks, that patch file was exactly what I needed for it to work properly - I had rebuilt it at the same time and it worked without issues.

Good to hear.
Actually it’s made me realise I have to update my Mint boxes. So thanks to you.

The patch brings back the indicator (/sys/kernel/realtime) that LinuxCNC uses to check if the OS is realtime. This is a part of the realtime patches that didn't become mainline.

Yeah I posted that patch in my first post.
You taught me the way royka

A big thanks to royka for making that patch.

Just built 6.13 for x86 (which needed that patch)

Seem like it's got quite good latency on my test machine
(noticeably better than the 6.11 kernel I was running earlier)
