=> toutes les irq ne sont pas disponibles sur tous les ports pci...
donc quand on a un probl�me d'irq, soit on tente de le forcer dans le bios (s'il supporte �a), soit on essaye de changer la carte de port pci...
Elle est pas belle l'architecture PC :)
Globule a �crit :
Tu as pas un autre port pci de libre pour d�placer la carte ? Ou inverser 2 carte pci, car certaines cartes pci (ta carte usb ?) ne supporte pas "l'irq sharing" ...
2005/5/13, Adeimantos <[EMAIL PROTECTED]>:
Apr�s avoir d�sactiv� dans le BIOS la prise en charge ACPI (�tant donn� que les chipsets VIA sur les cartes m�res Apollo ne permettent pas la gestion ACPI), enlev� les paquet Ubuntu acpi, acpid, powermangmt ... la carte PCI (HUB) Lucent Microelectronics 4 ports est bien reconnue au d�marrage du syst�me, ainsi que chacun des ports. Mais apparemment, ce que je soup�onnais semble �tre r�el : un conflit d'IRQ (mauvaise prise en charge du port PCI ?).
