I think this was in fact a red herring.  Yesterday I took the debugging 
options away and booted and the system still booted normally.  I've just 
tried booting the system today and it's back to the slow boot.

I've done this and it seems to fix the problem (both with and without 
serial debugging enabled).  I'll try a few times over the next day or two 
just in case the problem has only gone away temporarily...
