kernel BUG at fs/btrfs/inode.c:149!

Hi all,

Here's a traceback from a failed attempt to mount a btrfs in lvm in luks filesystem.

Note that if I mount it readonly it mounts successfully (haven't tried to recover any data as I have recent backups).

Yesterday I defragmented both / and /home with:

find /home -xdev -type f -print0 | xargs -0 sudo ./btrfs filesystem defragment -c

with btrfs-tools v0.19-35-g1b444cd and rebooted a couple of times. And today I got this traceback while trying to mount home at boot time (/ is working ok)

btrfsck fails with the following error:

couldn't open because of unsupported option features (8).
btrfsck: disk-io.c:682: open_ctree_fd: Assertion `!(1)' failed.

I'm using a 2.6.39-rc5+ kernel from Linus' tree.

If someone needs any extra info, just ask for it, Ill keep the corrupted filesystem for a few days before destroying it.

Thanks.

Elric Milon
