Well, that's a good question. The particular version I am running right now= is basically FreeBSD 9.0-CURRENT (well, from a free weeks ago anyway) with= lots of local kernel mods (to support drive pull primarily). I guess we co= uld very well be hitting a bug in this 9.0 code since it hasn't officially = been stamped as released...
