First thing I'd check is the shutdown sequence. I dunno if this is machine
you're physically in front of, but if you are, look for kernel output at the
end of the shutdown sequence.

The fact that it is rebuilding is usually indicative of an unclean shutdown.
If it happens all the time it might be that there is some problem preventing
buffers from being flushed properly and/or the gmirror to shutdown correctly.
