Beta 4 and diskless MD

[cliff]

I had a core/md and two diskless MD's running and then upgraded to Beta4.  Since then I have reinstalled the diskless MD the following two problems.  First, I had to reinstall the diskless MD's and each required several tries but finally succeeded. Secondly, when I shut down the diskless MD's and tried to restart them each will time out.  I have deleted them several times reinstalled with some failures and retries and finally got them to install again.  After turning them off, once again they will time out.
