This indicates a real time issue with network communications
(too many timed out packets)

FIxes

Use as better kernel

Best is 4.19 next best is 6.X 5.X are mostly terrible

Lower the servo thread rate (to say 2000000 ns)

I should also mention that if you have a Intel MAC
you need to disable IRQ coalescing as described
in the hm2_eth manual page.

Try Debian Bookworm which puts you on the 6.1 kernel
Follow my guide linked here.

Its hard to recommend going back to the 4.x kernel as a lot of later hardware is not supported.

You can try it. If it does not work out you can revert to your previous kernel by selecting a different option in Grub
