This, or even 9000, does not change behavior of my Canon MV5i.

firewire-ohci's debug logging only shows complete transactions going back
and forth, AFAICT (outgoing write transactions to FCP_REQUEST, incoming
write transactions to FCP_RESPONSE; both are split transactions and block
writes or quadlet writes).  Seems like this needs to be debugged at the
AV/C level.  The gscanbus crashes let me suspect that the camcorder sends
malformed FCP frames.
