Todas as conexões de rede foram descartadas depois disso. Sistema ainda inutilizável.
Somente após o boot com o velho linux-image-3.16.0-46-generic, meu servidor de e-mail de produção pode funcionar.
É um erro crítico para mim, alguém pode me ajudar?

Eu decidi mudar para um novo kernel vívido, que é o padrão no caso de uma instalação limpa para o Ubuntu 14.04.3 LTS:
sudo apt-get install linux-signed-generic-lts-vivid
no meu caso, porque tem UEFI BIOS e
sudo apt-get install linux-generic-lts-vivid
no caso de BIOS legado.
Os kernels utópicos podem ser removidos.
O mesmo problema aqui após a atualização para o 3.16.0-48.
Estamos usando servidores Intel S2600GZ4 com 4x Intel I350 Gigabit Ethernet. Tivemos que forçar o Grub a inicializar o 3.16.0-46 para resolver o problema.

Estou adicionando minha experiência a este tópico para torná-lo mais completo.
Minha experiência é a mesma que o adaptador de rede tornou-se praticamente inutilizável após a atualização para o kernel 3.16.0-48. Eu não consegui nem completar um apt-get update .
Eu segui este tópico para executar o comando ethtool -K eth0 gso off gro off tso off . Então eu completei com sucesso um apt-get upgrade para atualizar o linnel ternel para 3.16.0-49. O problema desapareceu depois de uma reinicialização. Não tenho certeza se o comando ethtool -K eth0 gso off gro off tso off ajudou nesse ponto.
A minha conclusão foi que ainda é possível executar um apt-get upgrade mesmo se você não concluiu um apt-get update .
