I'm getting this irq 9 problem with my home workstation. About 6 PCI devices are all using irq 9 and the option to change it manually is always greyed out. Is this some kind of special use of irq 9 for ACPI computers? I'm gonna try to force irq 9 to ISA in the bios to see what happens.
The only problem I have is my machine keeps hanging which I am putting down to the beta G400 drivers atm.
