If this is still a problem then please:
1/ get the latest mdadm:
     cd /tmp
     git clone git://neil.brown.name/mdadm
     cd mdadm
     make
2/ stop the array
     ./mdadm --stop /dev/md0
3/ force-assemble the array with --verbose:

     ./mdadm --assemble --force --verbose /dev/md0 /dev/sd[abc]1 /dev/sd[de=
fgi]

and report all the output of the last command.
