I just updated on my -STABLE machine and ran into the same exact problem.
I also have on the machine SMP with APIC. The fix for this problem is
simple:
Index: dpt_pci.c

rid = 0;
- irq = bus_alloc_resource(dev, SYS_RES_IRQ, &rid, 0, ~0, 1, RF_ACTIVE);
+ irq = bus_alloc_resource(dev, SYS_RES_IRQ, &rid, 0, ~0, 1, RF_ACTIVE | RF_SHAREABLE);
if (!irq) {
device_printf(dev, "No irq?!\n");
error = ENOMEM;
(Everybody in unison, say "Doh!")
Since this didn't change in the past two months, I'm guessing this was
caused by somebody else futzing with APIC. In any case, I don't see why
the DPT card shouldn't be allowed to share IRQs, and I'm now running the
latest -STABLE on my DPT card.
PS. Sorrry Matt for foiling your evil plot to get a free RAID card. ;)
