To be honest, I'm a little lost now. This last line looks like where the bug is,
but again, if this is the bug, I can't see a reason why the patch worked on it.

Can you run the following command on the device that you create a partition for?
sudo udevadm info --path /sys/block/dm-0 --query=all

Where dm-X is your device.
