Some update.
I tested with kernel 3.13.2 and still have the problem.
Also, I don't have the errors in kernel log anymore but now I can't delete my
snapshots!
melforce mnt # ls btr2
home vap-snap1 vap-snap2 var
melforce mnt # btrfs sub list btr2

melforce mnt # btrfs sub delete btr2/var-snap2
ERROR: error accessing 'btr2/var-snap2'
My /mnt/btr2/var is also mounted on /var.
There's plenty of space left on device (only ~590 GB allocated on 2.6 TB
volume):
