Isso é um erro no driver e1000e, é discutido aqui: link
% bl0ck_qu0te%Tenho certeza de que o uso do driver mais recente da Intel corrige seu problema .
Após realizar atualizações no meu recém-instalado Ubuntu 14.04 no Lenovo T440p, a conexão Ethernet pára de funcionar. Agora não tenho como conectá-lo à internet (o wi-fi nunca funcionou. Eu planejava lidar com isso em seguida). Como descubro o que está errado?
