and post the results here?

first make executable with:

chmod +x edrivers.txt

then

./edrivers.txt

So looks like the DKMS driver (I think the default driver with latency issues "8169")

So not sure whats going on.

What does your kernel command line look like?

cat /proc/cmdline

Did you try pinning the Ethernet IRQ?

As a test you can run this script:

 

File Attachment:

File Name: pinirq_2024-11-14.txt
File Size:668 B


chmod +x pinirq.txt then:

sudo ./pinirq.txt enp2s0

And then retry LinuxCNC or the ping test
