I appreciate that you spend time on it, but my feeling is that it 
definately isn't reproducible in all environments (otherwise we would
probably have seen a large cry by now).

I'm trying to bisect the "fix" down and hope that'll tell us something 
more.

If you do the test, remember, that it is not like "bonding isn't 
working". It just fails to initialize correctly at bootup and doesnt get 
  the link state by itself. Subsequently doing a /etc/init.d/networking 
restart brigs it correct up.
