Remover avisos ECC no log do sistema

Question

Como posso desativar esses avisos sobre ECC? Eu não tenho memória ECC e então desabilitei-a na BIOS também, mas ela ainda imprime.

Se você não tiver uma memória compatível com ECC, você pode tentar localizar e posteriormente desabilitar este módulo com spam:

find /lib/modules/$(uname -r) -type f -name '*.ko' | grep _edac

Haverá muitos *_edac*módulos, mas no seu caso o módulo culpado é amd64_edac_mod(conforme sugerido na mensagem de erro).

Então tudo que você precisa fazer é colocar este módulo no arquivo da lista negra:

echo "blacklist amd64_edac_mod" >> /etc/modprobe.d/blacklist.conf

Reinicie, voilà! — o módulo não é mais tentado a ser carregado e o erro desaparece.
