Just for the heck of it, you might want to try my patched md script and see if it works better for you. See bug #48756. Please not that in the attached script, there's a typo on the last mdadm line: it really should be '--assemble' where it says '-assemble'. Also, the output doesn't get redirected, but that's not critical. It'd be nice to hear if it works out for you :-)
