@Dustin -- it appears there is a whole bunch of change in this area to allow the raids to be created on the fly. I suspect that this is occuring becase mdadmin made the raid with all devices which then failed, but did not clear it down before rebuilding it in degraded mode, and as such a disk was already attached to the md0.
We need to find out what command sequence is being applied here in both the normal case and the degraded case, ie. exactly which commands have been attempted.
