I have just done a fresh clone of machinekit, built on a rt-preempt
kernel (with a posix) one also installed and I get

If your kernel does not say it is RT and PREEMPT, then it probably
isn't.

I compiled from source, using

I randomly gave a look in the /var/log/linuxcnc.log file
and I found that

Thanks Schooner.
Latest update worked.
For other people using the raspberry pi. I used the
ready made image from RealtimePi.
saving a lot of time for patching the preEmpt
realtime kernel
