Schrittmotoren brummen im Stillstand

Where can we get (6.3-rc5-rt8)

We can get it here
git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git
but I haven't figured out how to install it, yet.

I did something here
forum.linuxcnc.org/38-general-linuxcnc-q...ishing-read?start=10

So I got 6.3-rc5-rt8 up and running. What a ride...

I double checked hostmot2 + hm2_eth
Checked coalescing is off

Sadly still the same ping. I am close to just buy another intel NUC or something similar in size. Any recommendations?

By the way, it is this PC:

Intel NUC Celeron N5105 Mini PC

Are you sure all power management options are disabled in the BIOS?

Also any network related Intel MEBx BIOS options should be disabled (like AMT)

A kernel command line this may help:

quiet splash intel_idle.max_cstate=1 processor.max_cstate=1 idle=poll intel_idle.max_cstate=1 i915.enable_dc=0
