Ideally, world and kernel being out of sync shouldn't cause instability of
this sort.  Typically, it might result in tools such as ps, top, or maybe
ipfw not working as desired, but not hangs.  If you could confirm the last
date you had a kernel that didn't have instability problems, we can try
and track down what change it is between then and now that caused the
problem to arise.
