Hello tout le monde,
Je suis sous Debian Wheezy 64bits depuis peu (3.2.0-4-amd64 #1 SMP Debian 3.2.32-1)
J’ai un problème de conflit IRQ. J’ai lu que je devais faire en sorte de désactiver ce qui rentrait en conflit.
Le problème, c’est que d’après ce que je vois, ma carte graphique, ma carte son et une prise firewire sont en conflit.

Question :
Comment savoir ce que je dois désactiver précisemment ? Si c’est vraiment un port firewire, je l’utilise pas, donc je peux le désactiver. Par contre, pour la carte audio ?
Merci.
