:-( Something is walking on memory after freeing it, but it's not
immediately clear what.  If you boot single-user and don't mount file
systems, etc, does running commands result in a panic?  Assuming for a
moment that it doesn't panic, it would be interesting to try mounting nfs,
etc, incrementally until it does crash.  If it does panic even from
single-user mode, it sounds like some incremental backouts are called :-(.

If you back out a week or so (is that possible?) does life get better?
