kern/118093: firewire bus reset hogs CPU, causing data to be lost

Sean>  Which file in dev/firewire are you looking at?

fwohci.c  and  firewire.c

examples:

printf("non CYCLEMASTER mode\n");

device_printf(fc->dev, "Initiate bus reset\n");

With the printfs, Ethernet is not getting serviced.  This
is repeatable and easily reproduced.   Without the printfs,
it seems ok.

If it isn't spl, what is locking out Ethernet?
