  The command I'm using to assemble the RAID looks like the following:
     mdadm --assemble /dev/md14
--uuid=c9cc5194:50e0de0d:af3b7236:a60790c9
--update=super-minor /dev/mapd145:1 /dev/mapd149:1 /dev/mapd153:1
/dev/mapd157:1 /dev/mapd161:1 /dev/mapd165:1



It seems that the kernel does not have any knowledge that device type 7e should be handled differently. the disk driver should define a correct minor_shift which will allow md to know if two devices are on the same physical disk or not.

fix your disk device driver. or at least tell us which kind of hw it is.
