Error finishing read! Mesa 7i76e

Hello,
I get the error mentioned when a milling operation has run to completion or when I stop an operation with the stop button.
I have attached some pictures. My Mesa card is connected to a USB-LAN adapter.
Thank you very much for your help.

I just switched MESA connection from the USB-LAN adapter to the intern LAN adapter and the error is gone... the reason i didn´t take the intern LAN was my post monthś ago forum.linuxcnc.org/9-installing-linuxcnc...to-connect-to-github but now it also works.

1. USB-LAN adapters should not be used on production machines, USB has inherent latency issues
2. from your explanation it seems like interference issues, so is the machine and PC properly grounded?

Itś all good now. Thanks
