Short update:

Now repeated a clonezilla run without the USB-C NIC, but saving the image to a USB-C M.2 enclosure.
I see the same errors as before.

Ran another cz test, using only the USB-3 socket and saw no errors.

Finally just booted the ubuntu system from the m.2 USB-C enclosure and did see the errors.

And one for the road: Installed the m.2 disk internally and booted. Saw no errors.

So this is about USB-C in general, not the NIC specifically and not the PCIe.
