Esta pergunta é uma continuação de este .
Tenho tido muitos problemas com meu driver de chipset Ethernet e e1000e:
02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller
Aparentemente, não funciona de forma alguma sem pcie=off , e mesmo com a opção não funciona depois que eu retomo uma suspensão. Alguém tem algum conselho sobre isso? É um bug do upstream? Aqui está o que acontece quando tento retomar e usar minha placa Ethernet do dmesg.
Se você deseja ver os resultados de várias ferramentas de diagnóstico, confira minha pergunta anterior, que tem uma grande quantidade de informações sobre minha configuração .
