De la nada, mi segundo puerto Ethernet dejó de funcionar. Ambos son parte de la placa base.
Puedo ver ambos puertos en BIOS. Estaban funcionando, pero hasta ahora solo estaba usando uno de ellos. /etc/network/interfaceestá configurado correctamente y cambió la configuración entre eth0 y eth1.
sudo modprobe tg3tampoco ayudó (ya que en la documentación dice que este es el mod para los dos puertos/tarjetas Ethernet).
¿Es una causa perdida, ha salido mal o se puede solucionar?
