Eliminar las advertencias de ECC en el registro del sistema

Question

¿Cómo puedo desactivar estas advertencias sobre ECC? No tengo memoria ECC, por lo que también la desactivé en BIOS, pero aún así la imprime.

Si no tiene una memoria compatible con ECC, puede intentar encontrar y posteriormente desactivar este módulo spam:

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

Habrá muchos *_edac*módulos, pero en su caso el módulo culpable es amd64_edac_mod(como se insinúa en el mensaje de error).

Entonces todo lo que tienes que hacer es poner este módulo en el archivo de la lista negra:

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

Reinicia, ¡voilá! — Ya no se intenta cargar el módulo y el error desaparece.
