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.
