Best thing you can do it report it and hope some maintainer notices and hel= ps out. Oh wait, you did that :-) Looks like: commit 7bfec5f35c68121e7b1849f3f4166dd96c8da5b3 is at fault. It causes md to attempt to add spares into the array more oft= en. Would I be right in guessing that you have one spare in this array? If you remove the spare, the messages should stop. I think I know how I'll fix it but it'll have to wait for tomorrow. Then I'll send you a patch to test.
