Erros de placa de rede após a atualização do squeeze para jessie

Question

Nós atualizamos um de nossos roteadores centrais, que estava terrivelmente desatualizado, via apt-get dist-upgrade do Debian Squeeze sobre Wheezy para Jessie.

Mas agora vemos os seguintes erros em dmesg :

Isso acontece para todas as interfaces, que são de fibra ótica de 1 Gbit, a cada 2 segundos.

Alguns usuários até relataram uma conexão instável.

O que isso significa? É por causa de hardware desatualizado?

Estamos planejando comprar um novo, mas como podemos resolver o problema até que o novo roteador esteja disponível?

    

Answer 1

O motivo do erro pode ser um bug no kernel atual.

Nós fizemos o downgrade do kernel para 3.2.0-4 e ele funciona novamente.
