Subject: PCI devices sharing IRQs

Hi,

As already written in another mail, I have trouble with IRQs on one
system. A slightly unrelated issue is that most of the PCI slots appear
to map to the same IRQ, and I'm wondering if anything can be done about
this.

There are no BIOS options dealing with IRQ routing, all I have to go by
right now is the kernel log, which I've attached. If there is anything I
could try to change in order to give each card its own IRQ (especially
pulling the RAID card and the Ethernet controller apart could possibly
be worth something, as would handling IRQs on more than one core), I'd
be grateful for hints.

   Simon
