A placa de rede (realtek gigabit ethernet) não funciona, não envia nem recebe pacotes. Há uma mensagem de erro dizendo algo sobre um tempo limite da fila de transmissão. Estou incluindo alguma saída que pode ser relevante. Eu tentei pcie_aspm = off, rmmod + modprobe, mas nenhum indício.
Alguém pode ajudar por favor.
Obrigado
Martin
