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[defgi]
and report all the output of the last command.
