Ok, sounds good, just checking. :)  Can you provide the output of mptable for
this box?  In the SMP case, -current does interrupt routing for PCI interrupts
a bit differently, which might be a possible reason.  Hmm, but you are getting
interrupts eventually it seems.

Actuually, KTR is your friend here. :)  Read the ktr(4) manpage, then compile a
kernel with KTR_MASK and KTR_COMPILE set to KTR_INTR|KTR_PROC.  Then when it
hangs, break into DDB and look at the longs via 'show ktr' to see if you can
locate any interrutps coming in from ahc0 or ahc1.
