6.0-BETA4 #0: firewire problems

Hi,

Sorry for bugging you. I have a problem with firewire/dv that seems not
to have been noticed on the list, nor is reported. Before I file a PR, I
hope you could help me get better debug information.

System upgraded today to 6.0-BETA4 #0 but it appeared also with BETA3. 
On fortunately, I don't have anoter -STABLE system to try on so I can't 
exclude the problem may be more general.

The firewire device is a Canon MVX200 mini-DV camera. I have just bought
it so I can't exclude this is a problem with the camera rather than the
system.

Problems:

1) If the firewire device is connected on boot, system hangs booting
after identifying disks and before attempting to mount root device.
Once the firewire device is turned off the boot process resumes.

2) Connecting the firewire device, fwcontrol cannot read the DV stream. 
(see output below).

3) The connected firewire device can cause other applications, including 
firefox, thunderbird, mysql or login, to coredump in which case the 
system must be rebooted before it can be restarted.

If I'm missing something obvious, please tell me, I can go beat myself 
up just fine.

Thanks, Erik

Connecting the firewire device creates the following output (from
/var/log/messages):
