Your screenshot shows at least two interesting messages:

Code:

INTEL 0xdd1e8 unexpected ICR 00040000
...
INTEL 0xdd1e8 unexpected IXR 00000106

Assuming that the bits in this register are the same for i210 and i219, then the first of these (00040000 = bit 18) is "manageability event detected". This suggests that something has upset the Intel management controller (which is not part of the NIC, but does attempt to use the NIC via various sideband mechanisms).

You could try disabling the Intel Management Engine (or whatever it happens to be called on your system) within the BIOS setup screen.
