just as a followup, ryan on #ardour pointed out the kernel boot argument
"acpi_irq_balance" which results in *much* better distribution of IRQs

yenta and HDSP driver on the same IRQ, but i used to have the ethernet
and two other devices there as well. others who tried it reported
improvements as well.

But at this point, the interrupt lines from onboard and external PCI
devices are already merged, so changing the IRQ would just move
both devices.
When an onboard device and a PCI card conflict, you have to move the
card to another slot (or, better, to fix the driver(s)). Has it ever been possible to change the IRQs of
onboard devices? I
thought it was hard wired.
the wiring into the IO-APIC is board-level, but the IO-APIC is
programmable and thus you can change the actual IRQ that the device
generates, in theory.
