According to my memory all interrupts are serviced by the IOAPIC. The first 16 by the first IOAPIC, 17+ (everything behind the "PCI-bus") by the second IOAPIC. For that reason I didn't see a reason for the legacy PIC and set it to null_pic. Due to the timer problem it is delayed. > Thanks, > > tglx Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
