Hello folks.  I've been trying to use the ieee1394 code in -current
for about six weeks, since 1.6T, on an I386 system.  I can compile the
entire source tree, and run a generic kernel, but if I compile a kernel
with the fwohci driver in it, the kernel hangs on boot.  As it turns out,
the fwohci card and the USB controller share an interrupt and ddb shows
that when interrupts are enabled after autoconfiguration, the system is
hanging in a loop in which the interrupt drivers are called for these two
drivers over and over again.  It's as if a spurious interrupt is generated,
which neither driver recognizes, so they each return 0, which means keep
looking for the correct interrupt handler, but there isn't one, so try
again.
	I'm pretty sure this worked fine on 1.6P, and I haven't seen any other
complaints like this on current-users or port-i386.
	This is a board with one of those via Technologies chip sets, and the
USB controller is part of that chip set.  The fwohci card is a Lucent card.
	Anyone have any ideas on how to troubleshoot this further?  Dmesg for
GENERIC is posted below.
-thanks
-Brian
