The Kernel seems to recognize the gigabit ethernet card and displays:

Intel(R) PRO/1000 Network Driver - version 3.1.23
Copyright etc...

It actually displays this twice. However when I try to config the interface:

ifconfig eth0 192.168.1.100 netmask 255.255.255.0

I get:

SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device

when I cat /proc/pci I can see the details of the NIC.

Any suggestions?

Thanks in advance.
