I had this issue on a RAID 10 with f2 layout with 3 disks. After upgrade from intrepid to jaunty (production) RAID(s) 1 were fine, but RAID 10 was inactive with only sdc(4) showing.

Fix was rather simple, only:
$ sudo mdadm --stop /dev/md_d2
$ sudo mdadm --assemble --scan

Result:
   /dev/md2: File exists
   mdadm: /dev/md/2 has been started with 3 drives.

and then:
$ sudo mount -a

and array was back...
