Adaptect SCSISelect Util showed:

    Adaptec AIC-7899 Channel A IRQ 11
    Adaptec AIC-7899 Channel B IRQ 10

Qlogic FastUtil! showed the 2200 fibre card using IRQ 10 as well.

List of IRQ usage on my system grep from dmesg:

isp0: interrupting at ioapic1 pin 7 (irq 10)
amr0: interrupting at ioapic1 pin 9 (irq 11)
isp1: interrupting at ioapic1 pin 5 (irq 5)
ahc1: interrupting at ioapic1 pin 1 (irq 11)
ahc2: interrupting at ioapic1 pin 2 (irq 10)

rccide0: primary channel interrupting at ioapic0 pin 14 (irq 14)
rccide0: secondary channel interrupting at ioapic0 pin 15 (irq 15)
ohci0: interrupting at ioapic1 pin 15 (irq 11)
lpt0 at isa0 port 0x378-0x37b irq 7
com0 at isa0 port 0x3f8-0x3ff irq 4: ns16550a, working fifo
com1 at isa0 port 0x2f8-0x2ff irq 3: ns16550a, working fifo
pckbc0: using irq 1 for kbd slot
pckbc0: using irq 12 for aux slot
fdc0 at isa0 port 0x3f0-0x3f7 irq 6 drq 2

I know on Windows, sometimes cards can share IRQ's as long as they have 
different "resource I/O range."

Somtimes during kernel bootup, it would get stuck at the isp0 with 
similar errors as for isp0 and end with a "probe(...)" and it hangs.
