Yup, the kernel versions are drastically different. It's 3.10 vs 4.2. The problem on 3.10 though is, while jbd2 holds on to the unmounted device I cannot even rmmod jbd2 or ext4 *even if no other ext filesystems are mounted*. That lock makes it all but impossible to do anything with the block device.
