Sporadic total failure of kext about atherose2200ethernet HOT 7 CLOSED

I need kernel logs showing the incident in order to find out what is going on.

Okay, how do I get it? Sorry, never did it before

The driver fails to get the NIC's MAC address as the error message states:

Ethernet [AtherosE2200]: Failed to get permanent MAC address.

AFAIK this is either a hardware issue or due to a wrong BIOS setting but I don't know how to resolve it.

The funny thing is, it shows this error even on ALXEthernet. So 1. I screwed up when changing kext or 2. there is something weird going on.
Because I changed literally no settings, nothing in BIOS and one day it worked, second day it stopped working

UPDATE:
After some time with ALXEthernet I switched back and it works again. I changed nothing and there is no error regarding ethernet in system log. ¯(°_o)/¯
