Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

Issue start happening after moving system from ext4 partition to btrfs partition. btrfs wasn't used before.

According to Kernel Buzilla that bug should be fixed in btrfs-next: https://bugzilla.kernel.org/show_bug.cgi?id=60793

The v3.12-rc1 kernel was just released. Can you also test this kernel to see if it exhibits this bug:
