this problem occured here when /var/run/network/ifstate is on a RW
persistent storage and not in a tmpfs : the interface state can exist
when booting after a dirty reboot.

A workaround is to hack
meta/recipes-core/init-ifupdown/init-ifupdown-1.0/init and add
ifdown -a
just before ifup -a in the start) section
