It strikes me that the arcmsr0 is the only thing that interrupts at
ioapic1 (one) where everything else interrupts at ioapic0 (zero).

; (keep-lines "ioapic" nil nil t)

This could be related to the fact that the Areca board sits on a riser
card, with a sturdy IC (its heatsink covers its markings) on it. I
wonder if that riser card is the culprit. The lack of room prevents me
from mounting it directly on the MB, so I guess I will have to be
inventive somehow ... :-(
