You have a case of bad ju-ju.

I ran into the same upgrading to 10.10.   I use firewire just for
channel-changing, but intermittently the firewire bus would just lock
up....  only pulling the cable and re-inserting it, or powering off and
on, would fix it.  (unloading/reloading the modules wouldn't clear it.)

You have a choice of blacklisting juju and going back to the old stack,
or changing your firewire card.

In my case, I was using a cheap PCI firewire card.  I upgraded my
motherboard, and have been using the firewire port on the motherboard
with no issues.
