I added a comment about this new fix on https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1608495. One thing I wanted to add here, for the first time shutdown completed successfully. In fact, I was a little startled when it happened. :-) It powered off at the end of shutdown, instead of hanging at the "Reached target Shutdown" message.
One question: Does this mean that Ubuntu 18.04 will use mdadm by default during installation instead of dmraid? I really hope so. It's a real pain to do it manually.
