SATA RAID, tested again, blaming IRQs

[Rio Baan]

Tried applying some boot parameters to FC test2 on this hardware with built 
in SATA RAID.
Boot params were: acpi=off, apm=off, pci=userpirqmask, pnpbios=no

None worked.... on either SMP or single CPU kernel.

What I DID notice was some funny goings on in the IRQs of the SATA drives.

The SMP kernel automatically sets the IRQs for both drives on the RAID to 
209 (and I don't believe that's valid)
The single CPU kernel sets both IRQs to 9

acpi, and apm off didn't really change anything
pci=userpirqmask swapped the IRQs to 209 where it would have been 9.

In either case, neither setting worked. 9 crashed the system outright. 209 
crashed the system, but the swirling dots during the grey init screen kept 
going.

Here's my board's IRQ placements. I haven't tinkered with the boards default 
IRQ settings either. Seems like a lot of stuff is sitting on IRQ 
number9..... number9...... number9.....number9...........
