    Thanks Jeff (quick response)

    > > IRQs are assigned by firmware. Try turning on/off io-apic or ACPI.

    If IRQ's are assigned by firmware then why does Windows 2K3 assign an
    IRQ per port and Linux not?

    If I can get Linux to assign 1 IRQ per Ethernet port then my system will
    magically work (it does under Win2K3).

    So, I am asking if there is a way to assign 1 IRQ per Ethernet port in
    the same manner as Windows?

    I have a service call in with IBM to see if there is a way I can change
    from MP1.4 to MP1.1 as suggested in the SMP-HOWTO (there is no menu
    option for this) and then I can use the noapic/acpi=no options, but I'd
    rather not as this will limit the number of IRQ's available.

    Many thanks,

    (FYI no additional information has been posted because I can not get
    into the machine across the network without these interfaces in order to
    retrieve the files suggested in REPORTING-BUGS) and there is no floppy
    permitted.
