Eu tenho um servidor com uma placa-mãe da Asus P9D-I. Tem duas placas de rede Intel:
# lspci -nn | grep Eth
01:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:1533] (rev 03)
02:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:1533] (rev 03)
O servidor está executando o Debian wheezy com o kernel backports mais recente:
# cat /etc/debian_version
7.2
# uname -a
Linux hostname 3.10-0.bpo.3-amd64 #1 SMP Debian 3.10.11-1~bpo70+1 (2013-09-24) x86_64 GNU/Linux
# dpkg -l | grep -E '(linux-image-amd64|linux-image-3.10)'
ii linux-image-3.10-0.bpo.3-amd64 3.10.11-1~bpo70+1 amd64 Linux 3.10 for 64-bit PCs
ii linux-image-amd64 3.10+52~bpo70+1 amd64 Linux for 64-bit PCs (meta-package)
As interfaces ethernet do aparecem em ifconfig -a :
# ifconfig -a
eth0 Link encap:Ethernet HWaddr ac:22:0b:8b:30:a7

[...]
Mas, por algum motivo, não consigo usá-los para nada:
# ifconfig eth0 up
SIOCSIFFLAGS: No such device
# ifconfig eth1 up
SIOCSIFFLAGS: No such device
# ethtool eth0
Settings for eth0:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available
# ethtool eth1
Settings for eth1:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available
dmesg não parece ter nenhuma saída interessante do driver igb responsável:

Alguém sabe o que pode estar errado aqui e como posso fazer com que essas NICs funcionem? Se for possível fazer isso sem compilar manualmente kernels ou drivers, eu preferiria isso.
