There's a report of excatly the same failure mode on mac53c94 with a
different brand (Sony, as opposed to Yamaha on my MESH) of DVD drive.
So the only points in common seem to be that the DVD drives are running
on mac hardware and that the drivers are written by Paul Mackerras.  :-)
I don't at all mean to impugn Paul's coding ability, which is obviously
excellent, but the fact that he wrote both the drivers may mean that
they share lots of code and possibly share the same bug.
