I actually figured out the problem. I had gmirror on the machine, and was booting to do maintenance using non-gmirror kernel sometimes. One kernel was using ad4, the other using ad6, and one using gm0(ad4/ad6). Kernel modules and kernel were consequently getting out of sync. Problems are fixed now -- I'm currently being amazed by the SMP performance, kqueue, and some threaded python...doing as much on 2 old machines from 2005 and freebsd with optimized python as we were doing with 55 linux machines running badly tuned php5 in apache.
