novo sistema com erros do pcie precisa de ajuda na depuração

Question

Estou recebendo alguns erros e esperava que alguém pudesse ajudar a depurar. O que significa primeiro e segundo qual é o meu caminho para investigar mais etapas de depuração e uma solução completa, se possível.

Executando a placa-mãe Aorus Gaming 7 com uma CPU Threadripper 1950x e Nvidia 1070 com os drivers mais recentes.

Aqui está um link para a pasta

Answer 1

Parece que esse problema acontece em muitas placas-mãe de x99 na Intel para x399 na AMD.

Eu posso dar pelo menos alguns detalhes, mesmo que eu não possa explicar completamente o que acontece.

Eu pensava que o TLP era um problema de energia, mas depois de uma pequena pesquisa descobri que ele realmente significa pacotes de camada de transação (TLPs).

O hardware geralmente detecta pacotes defeituosos, e o kernel Linux reporta isso como mensagens.

A opção do kernel pci = nommconf desabilita o Espaço de Configuração PCI Mapeado na Memória. Você pode adicionar isto editando o grub com este comando.

sudo nano /etc/default/grub

Encontre a variável GRUB_CMDLINE_LINUX_DEFAULT e adicione a linha abaixo nas aspas no final.

pci=nommconf

Meu parecido com isso depois.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nommconf"

Isso pode ser um bug de hardware nos dispositivos, no controlador ou em algo totalmente diferente.

Embora esta seja uma solução real que resolve os erros e não apenas os suprime, o que, sem muito mais conhecimento técnico, parece uma boa solução. Embora pessoalmente eu procure por mais atualizações de BIOS da placa-mãe junto com as atualizações do kernel e remova temporariamente a alteração para ver se ela está resolvida.
