I'm redirected from the mailing list: http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg24919.html System: Distributor ID: Ubuntu Description: Ubuntu 13.04 Release: 13.04 Codename: raring Linux ctu 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux The symptom is the same with Saucy 3.9 kernel. With kernel from git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-next.git I'm not able to mount at all, no oops, it behaves, like it would not be a btrfs partition.

One more thing. Now the machine is completely freezing, when if I mount the partition, so I cannot paste am oops message with not tainted kernel.
Ok you'll need to do btrfs-zero-log /dev/whatever and you will be good to go. Please re-open if that doesn't fix your issue.
