ITE8212 RAID Controller - unable to allocate IRQ

[Hannes Mayer <fedora@xxxxxxxxxxxxxxxx>]

Hi all!

I just recompiled kernel 2.6.6-1.391 (Arjan) with the ITE8212 driver as module.
Everything went as expected and the kernel installed fine.

But when I modprobe:
# modprobe -f iteraid
FATAL: Error inserting iteraid (/lib/modules/2.6.6-1.391custom/kernel/drivers/scsi/iteraid.ko): No such device

The kernel says this:
# dmesg
[...]
Found Controller: IT8212 UDMA/ATA133 RAID Controller
iteraid_init: unable to allocate IRQ for IT8212 UDMA/ATA133 RAID Controller
[...]

What can be done to set another IRQ ?
How can I check if there are any IRQ conflicts ? (all devices seem to perform fine)

Thanks a lot,
Hannes.
