Por favor, tente inicializar o kernel com o parâmetro do kernel pcie_aspm=off .
Atualmente estou tendo um grande problema com o e1000e (não funciona de todo) no Ubuntu Maverick (1.0.2-k4), depois de continuar estou obtendo muitas coisas no dmesg:

Também gostaria de observar que usei eth0 todos os dias durante anos e até recentemente nunca tive um problema.
Do driver do Intel, leia-me: downloadmirror.intel.com/9180/eng/README.txt
Diversos adaptadores com o chipset 82573 exibem mensagens "TX unidade travar" durante a operação normal com o driver e1000. O problema aparece tanto com TSO ativado e desativado, e é causado por uma função de gerenciamento de energia que está ativado na EEPROM. As primeiras versões dos chipsets para os fornecedores tiveram Bit EEPROM que ativou o recurso. Depois que o problema foi descoberto mais recente os adaptadores foram liberados com o recurso desativado na EEPROM.
Se você encontrar o problema em um adaptador, e o chipset for baseado em 82573 um, você pode 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) tem o bit 0 não configurado. Isso permite que a problemática recurso de economia de energia. Neste caso, a EEPROM precisa ler "df" no offset 0x001e.
Uma correção única de EEPROM está disponível como um script de shell. Este script irá verificar que o adaptador é aplicável à correção e se a correção é necessária ou não. E se a correção é necessária, aplica a alteração à EEPROM e atualiza o checksum. O usuário deve reinicializar o sistema depois de aplicar a correção se as alterações foram feitas para a 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!

Como coveiro, gostaria de desenterrar esse antigo segmento de bunda para compartilhar minha solução para o Ubuntu. Faça o download do driver de rede Intel mais recente ( 3.4.0.2 no momento da escrita). Descompacte-o, acrescente uma coisa a uma linha no Makefile, obtenha o patch, aplique o patch, instale, leia o módulo e, finalmente, reinicialize. Boa sorte.

sudo reboot
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. Eu atualizei o driver diretamente da Intel para o 3.4.2.1-NAPI, sem quaisquer melhorias. Todas as coisas listadas neste e no outro thread não ajudaram . Adivinhando ler este relatório de bug do Ubuntu eu percebi como uma solução para reduzir significativamente o tamanho do ringbuffer:
sudo ethtool -G eth0 rx 256 tx 256
Isso resolve o problema completamente para mim e parece não impactar o desempenho (uso na área de trabalho, somente benchmarks básicos).
