Prévenir le problème

Interdire au noyau d'accéder directement au matériel. Ce qui veut dire que le noyau doit se fier au bios, ce qui n'est pas forcément une bonne chose étant donné que les bios sont connus pour donner des informations plus erronées que valides.

/etc/default/grub

GRUB_CMDLINE_LINUX="pci=bios"

Regénérez le fichier de configuration après modification du fichier /etc/default/grub
