Just to confirm, did you disable the quotas in BTRFS? You can check this by
running the command:

    btrfs qgroup show /

All my problems related to this bug have gone after I disabled quotas. As I
pointed out in my comment #4, btrfs devs warned sometime ago that quota is an
unstable feature and we should avoid using it. However, it seems that you will
lost a YaST feature if you disable quotas (something related to auto-clean
snapshots IIRC).

I totally agree. If this bug is so hard to fix and depends on upstream, we
should really start to think about disable quotas by default in Leap at least.
