It seems that linuxbios (and linux) uses the irq routing tables
dumped from the bios mptable.
Are there any good reasons to reroute 9 pci/agp interrupts (2 64-bit slots
on the first pci bus + 1 agp + 4 32-bit slots + builtin ethernet on the
second pci bus) to 4 apic pins 16,17,18,19 when at least the pins 5,9,10,11
are not used at all ? Now i have 3 devices sharing
pin 19, and 2 devices on 16,17 and 18.
Is this the intended use of io-apic ?
