I recently encountered the same problem on kernel 3.8 with Archlinux, I'm running BTRFS in RAID1 and had pretty much the same problem. Mounting the volume resulted in this trace and no mount, trying to mount again would freeze and I would need to reboot to try again, I tried using clear_cache, recovery, ro without any success, tried btrsck --repair, it said it fixed something but fails to mount afterward and furthermore complains about space_cache being outdated. I had to use btrfs-zero-log before it could mount again.
