Do nada, minha segunda porta Ethernet parou de funcionar. Ambos fazem parte da placa-mãe.
Posso ver ambas as portas no BIOS. Eles estavam funcionando, mas eu estava usando apenas um deles até agora. /etc/network/interfaceestá configurado corretamente e alterou as configurações entre eth0 e eth1.
sudo modprobe tg3também não ajudou (já que na documentação diz que este é o mod para as duas portas/placas Ethernet).
É uma causa perdida, deu errado ou pode ser consertado?
