Hi again. Seems it was not actually that simple after all. Yesterday I 
had tested rebooting the server after just the base O/S had been 
installed and it was working fine so I assumed that was it. Today I have 
reinstalled all my ports and then decided to do one last reboot to make 
sure everything came up properly. And guess what? The same error 
happened again! I then tracked it down. It seems to happen when the 
mail/postgrey port is started. If I comment that out of rc.conf and 
reboot and let it mark the filesystem clean then I can happily reboot 
with no issues again. If I remove the comment and start it up then I get 
the same issue on the next reboot.

So there is something strange happening between the mail/postgrey port 
and 9.1-RC1 amd64. As greylisting isn't completely important I can leave 
this disabled for now but I would like to still resolve this issue so 
that I can use it again, unless there is alternative greylisting 
software that I could use with postfix.
