I built a Xenial test kernel with commit b8c0d911ac528. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1705493/ Can you test this kernel and see if it resolves this bug?

Also, the lack of that feature prevents dmcrypt usage as multiple partitions are created on a device in this case. Could that be backported to the 4.4 kernel?
