It's not that bad. I have seen 3 reports of problems, but
also a large number of successful uses (I use it on three
machines with 789x controllers without a hitch).

Actually, the driver in FreeBSD hasn't had any serious commits in
6 months now. But sure, we need to update ours. The main problem
will always be that we never got any docs for the thing, even
though we begged Adaptec. Porting the newer version will help
there, since it'll make pulling over fixes a lot easier.

I don't have any time at the moment to do this. I do not have any
notes from the last port, unfortunately. But, they would be
mostly useless anyway. Anyone who wants to port the new version can
look at aix7xxx_$OS.c, where $OS is FreeBSD, Linux, or also
OpenBSD now I think (I believe there is an OpenBSD backend now).

The effort would be to get to know scsipi(9) a little, it should not
be much work. But I won't be doing it anytime soon.
