:Hi Matt,
:Reading this makes me wonder, what does FreeBSD do about this issue? 
:They do not have APIC_IO option (as far as i know they have just option 
:SMP) and it seems to be relatively trouble free in regards to 
:IOAPIC/LAPIC: On DragonFly it seems to be an issue more often.

    They've moved the bar a bit more forward, but there are still problems.
    The main difference between FreeBSD and us is that FreeBSD has done
    a lot more work on supporting interrupt routing via ACPI.
