You're making the troubleshooting unnecessarily difficult by continuing to use non-default options. *shrug* Every single layer you add complicates the setup and troubleshooting. Of course all of it should work together, many people do. But you're the one having the problem so in order to demonstrate whether this is a software bug or hardware problem, you need to test it with the most basic setup possible --> btrfs on plain partitions and default mount options. -- Chris Murphy
