--- Comment #4 from Keve Nagy <***@nagykeve.e4ward.com> ---
I run into the same issue reported by OP. My conclusion is that the problem is
related to the particular firewire controller found integrated on the
motherboard of these Apple Mac computers.
Discussed in detail on

## PROBABLE CAUSE: The TI based Controller.
So, in this machine, using this firewire controller, everything worked fine as
expected.
My suspicion is that what trev bug-reported and what I experienced earlier, is
caused by the kind of firewire controller found integrated on these Apple Macs.
I am going to add these findings to trev's bug-report. Hopefully support for
these firewire controllers can be added to the FreeBSD codebase. This would be
particularly interesting in the PPC architecture, as G4 and G5 processor based
Macs can still be made useful by running a recent release of FreeBSD/PPC. But
equally apply to later model, Intel processor based Macs too.
To be considered: adding support for the firewire controller found on Apple Mac
computers.
