hi,
i've got the same problem "kernel BUG at fs/btrfs/relocation.c:1060".
this was solved by patching the kernel with following patch
https://git.kernel.org/cgit/linux/kernel/git/josef/btrfs-next.git/commit/?id=b6c60c8018c4e9beb2f83fc82c09f9d033766571
i've also found, that this patch is NOT included in 3.11.x stable
kernel tree. see here to confim the absence
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/fs/btrfs/relocation.c?id=refs/tags/v3.11.4
fous
