I don't know if that is because at the moment, /dev/md127 is auto-read-only:
bill@bill-desk:~$ cat /proc/mdstat

Again, md1 is an unrelated array that is functioning fine. I have the
same issues with md127 when md1 is disconnected.

I've been using them for some time with no trouble. I have the same
type cables on the other array that is fine. While troubleshooting, I
have unplugged and replugged the cables several times, both at the
drive end and the controller card end. Upon boot, the card always
reports the correct number of drives.
