Ok, with more debugging enabled, it seems that a Windows initiator is 
attempting to read ffff:f0000428 and failing.  I'm looking over sbp-2 
and I can't quite make out what that entry is supposed to be.  Here's 
the debugging output in full:

fwohci0: BUS reset
fwohci0: node_id=0x8800ffc0, gen=4, non CYCLEMASTER mode
sbp_targ_recv: cannot resolve nodeid=1
sbp_targ_recv: rtcode = 6 lo == 0x0
fwohci0: start AT DMA status=0
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1
fwohci0: maxdesc: 3
fwohci0: start AT DMA status=11
fwohci0: fw_set_bus_manager: 1->1 (loop=0)
firewire0: bus manager 1
