Something broke :-( Re: fwcontrol update

[Dieter]

Am I correct in assuming that none of this stuff that
fwcontrol sets should carry across a reboot?  And that
the firewire controller should get completely reset
by a reboot?

I'm getting some bad results.  Attempt to recover:

Changed symlink from current fwcontrol to known working fwcontrol_prev.
Powered off camcorder.
Rebooted FreeBSD.
Powered on camcorder.
Ran fix_dv script to get FreeBSD into "non CYCLEMASTER mode".
	fwcontrol -u 1 -f 0
	fwcontrol -u 1 -r
Start playing a tape (so I can run fwcontrol -R)

FreeBSD console starts spewing:

Stopping the camcorder stops the spewing.

Needless to say, fwcontrol -R no longer works.

I ran the fixit script again, and fwcontrol -S does work.

I notice that it doesn't print every generation.
I notice that the node_id changes.

FreeBSD 7.0
AMD64
fw controller: NEC uPD72871/2

Ideas?
