My PCI-Mode is (Any), I have APIC enabled CONFIG_X86_GOOD_APIC=y CONFIG_X86_UP_IOAPIC=y CONFIG_X86_IO_APIC=y CONFIG_X86_LOCAL_APIC=y And I use SCSI. I do not have any Problems.

Try to find out e.g. with xosview, which shows you interupts... -Marc -- +-O . . . o . . . O . . . o . . . O . . . ___ . . .
