You may have had some device names reordered.  Building a config that
relies on the names is common but unwise.

With such a thin report, there's not much to go on.  Please run lsdrv
[1] and paste its output in a reply.

Then add the contents of /proc/mdstat, the relevant-looking parts of
dmesg, and your mdadm.conf file.

We may need more later, but this will permit intelligent follow-up
questions.
