Hmmm.. I've got an old AXPpci33 system which shows, well, comparable
behavior: one of the PCI slots can't trigger interrupts there. I was
told that IRQ13 is routed to that slot, which gets ignored after
because IRQ13 was reserved for FPU on ia32. For my board, I can find
the table in ./linux/arch/alpha/kernel/sys_sio.c:343. (IRQ13 gets routed
to last slot). You'll find sth like that for your board you may want
to play with...
