This is a bug in raidstop.  If you strace you will notice that it
opens it twice and before trying to ioctl(STOP...) it.

Upgrade raidtools or use mdadm.

And a quick and dirty:

   mv /dev/md0 /dev/mdx
   mv /dev/md1 /dev/md0
   mv /dev/mdx /dev/md0
   raidstop /dev/md1
   mv /dev/md0 /dev/mdx
   mv /dev/md1 /dev/md0
   mv /dev/mdx /dev/md0

should work.
