Hmmm, sorry to hear about this happening again. 

The new kernel does not have any differences in terms of firewire
support, I'm still using the old firewire stack.

That's weird because I don't see how installing a kernel could change
the underlying libraries. The libavc/libraw upgrade you installed is
just a couple of libraries, they should stay the same when other things
are installed (I'm not saying you don't have a problem :-) 

I just donwloaded the two replacement source packages and libraw1394 is
indeed different - the original Fedora package has a patch for the
"juju" firewire stack which has been removed in the alternative package.
The libavc1394 package has no changes except for the release number
change, it just probably needs to be rebuilt with the old unpatched
libraw1394.

Could you check the libavc1394 and libraw1394 packages to make sure you
have the modified ones still installed?

"rpm -q libavc1394 libraw1394" should print the versions. 

Could you also check the integrity of the packages with "rpm -V package"
to see if there has been a change?
