This is really weird, after I installed the 2nd D-Link card and booted
up the server everyone could work again. But I noticed and eth2 being
loaded as well, which could only make sense if the onboard NIC was in
fact still working. And it was. So I took out the D-Link, deleted
eth2, rebooted and it worked again as normal.
Why would this happen, or have happened in the first place? Why would
a NIC just loose it's drivers like that?
