Problemas em Linux e1000e (driver de rede Intel) em abundância, por onde começar?

No momento, estou tendo um grande problema com e1000e(não está funcionando) no Ubuntu Maverick (1.0.2-k4), após o resumo, estou recebendo muitas coisas no dmesg:

Por favor, tente inicializar o kernel com o pcie_aspm=offparâmetro kernel.

82573 (V / L / E) Mensagens de travamento da unidade TX

Vários adaptadores com o chipset 82573 exibem mensagens "Unidade paralisada TX" durante a operação normal com o driver e1000. O problema aparece com o TSO ativado e desativado e é causado por uma função de gerenciamento de energia ativada na EEPROM. As primeiras versões dos chipsets para os fornecedores tinham o bit EEPROM que ativava o recurso. Depois que o problema foi descoberto, os adaptadores mais recentes foram lançados com o recurso desativado na EEPROM.

Se você encontrar o problema em um adaptador e o chipset for baseado em 82573, poderá verificar se o seu adaptador precisa da correção usando o ethtool:

 # ethtool -e eth0
 Offset          Values
 ------          ------
 0x0000          00 12 34 56 fe dc 30 0d 46 f7 f4 00 ff ff ff ff
 0x0010          ff ff ff ff 6b 02 8c 10 d9 15 8c 10 86 80 de 83
                                                           ^^

O valor no deslocamento 0x001e (de) possui o bit 0 desabilitado. Isso ativa o recurso problemático de economia de energia. Nesse caso, a EEPROM precisa ler "df" no deslocamento 0x001e.

Uma correção única EEPROM está disponível como um script de shell. Este script verificará se o adaptador é aplicável à correção e se a correção é necessária ou não. Se a correção for necessária, ela aplica a alteração à EEPROM e atualiza a soma de verificação. O usuário deve reiniciar o sistema após aplicar a correção, se forem feitas alterações na EEPROM.

Exemplo de saída do script:

 # bash fixeep-82573-dspd.sh eth0
 eth0: is a "82573E Gigabit Ethernet Controller"
 This fixup is applicable to your hardware
 executing command: ethtool -E eth0 magic 0x109a8086 offset 0x1e value 0xdf
 Change made. You *MUST* reboot your machine before changes take effect!

O script pode ser baixado em http://e1000.sourceforge.net/files/fixeep-82573-dspd.sh

Como coveiro, eu gostaria de desenterrar esse velho tópico para compartilhar minha solução para o Ubuntu. Baixe o driver de rede Intel mais recente ( 3.4.0.2 no momento da gravação). Descompacte-o, acrescente algo a uma linha no Makefile, obtenha o patch, aplique-o, instale, leia o módulo e, finalmente, reinicie. Boa sorte.

Este wad foi concluído no Ubuntu 18.04, kernel 4.15.

Eu tive o mesmo problema com um e1000e no kernel do Ubuntu 18.04.1, 4.15.0-36 e nada ajudou. Atualizei o driver diretamente da intel para 3.4.2.1-NAPI, sem nenhuma melhoria. Todas as coisas listadas neste e no outro tópico não ajudaram. Acho que lendo este relatório de bug do Ubuntu , imaginei como uma solução alternativa para reduzir significativamente o tamanho do buffer de anel:

sudo ethtool -G eth0 rx 256 tx 256

Isso resolve o problema completamente para mim e parece não afetar o desempenho (o uso da área de trabalho, apenas os benchmarks básicos).
