I have been using a Buslink 1394 Firewire HD model #FW80 72E on 2
4-STABLE systems for backup. The Firewire ports are onbord on an
ASUS P4PE and an ASUS P3B-1394 motherboard.
Mounting and unmounting works fine, I do have troubles with hot swapping
though.
On the ASUS P3B-1394 system
FreeBSD 4.9-RC cvsup'd and built/installed today

On bootup with my firewire drive plugged in everything is fine.
Unplugging the firewire cable gives this in my console:
fwohci0: BUS reset
fwohci0: node_id=0xc800ffc0, gen=2, CYCLEMASTER mode
firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me)
firewire0: bus manager 0 (me)
plugging the firewire cable back in gives this:
fwohci0: BUS reset
fwohci0: node_id=0xc800ffc1, gen=3, CYCLEMASTER mode
fwohci0: SID Error
At this point I cannot mount the firewire drive anymore.
I have tried using 'fwcontrol -r' but no luck.
Any help or pointers appreciated.
