The PPro local apic documentation says: <<<<<<< The processor's local APIC includes an in-service entry and a holding entry for each priority level. To avoid losing interrupts, software should allocate no more than 2 interrupt vectors per priority. >>>>>>>> Ok, we must reorder the vector numbers for our own interrupts (0xfb-0xff), but that doesn't explain our problems: we don't loose reschedule interrupts, we have problems with normal interrupts - and there we only use 2 irq at the same priority level. Btw, the kick patch I sent a few minutes ago revives my io apic. -- Manfred - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
