Hi Miguel,
btrfs guarantees backward compatibility since 3.13(?), but never
guaranteed forward compatibility. So it is not yet supported to mount
the fs with an older kernel once it was mounted with a newer one.
Especially when using features that are under heavy development right now.
Also try to keep your kernel up to date (3.13 is out since a few days)
Joshua
