Desde abril, quando construí meu computador com o Arch Linux OS, tenho recebido alguns erros que parecem apontar para o controle do ASPM de alguns dispositivos USB 3.1 na placa-mãe ASUS "ROG STRIX Z370-E GAMING".
Ou recebo 0, 1 ou ambos os seguintes erros após journalctl
, os erros parecem ser totalmente aleatórios, para verificar se os erros ocorrem ou não. Gostaria de salientar que os portos funcionam atualmente, mas o seu poder não pode ser modulado pelo SO. (Embora o Windows não tenha problemas.)
Minhas tentativas de solução de problemas levaram-me a desativar as portas USB afetadas no BIOS, o que corrige os problemas. Mas eu obviamente gostaria que as portas USB funcionassem.
Abaixo estão algumas informações de diagnóstico. Eu também coloquei a informação relevante em negrito.
