Interfaces de rede não reiniciam

Bom dia,

Estou com um leve problema nas minas placas de rede, elas sobm OK quando reinicio o comutador, mas quando uso o comando /etc/init.d/networking restart só a placa eth1 sobe:

Abaixo meu arquivo /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

iface lo inet loopback

auto eth1

Resolvido, descomentei as linhas de allow-hotplug, e substitui o allow-hotplug por auto.
