I had a similar problem when I was testing here (during the 3.4 kernel dev cycle, I decided btrfs was still too experimental for my current needs so am back on more reliable reiserfs for now), which turned out to be a corrupted space-cache. Mounting with the listed nospace_cache option allowed the filesystem to mount and self-repair, after which I could mount it normally again. https://btrfs.wiki.kernel.org/index.php/Mount_options -- Duncan - List replies preferred.
