I was using btrfs with openSUSE 12.1 and during the last update (glibc), the system hanged and I had no choice but to reboot. Now I can neither boot my system, nor mount my btrfs partition from a live USB, e.g. PartedMagic or the openSUSE 12.1 live CD images. Whenever I try mounting the fs, I get the following kernel oops: ------------------------------------------ # mount /dev/sda3 /mnt/ # dmesg [ 379.420110] Btrfs loaded [ 379.420430] device fsid dd1cdd10-6b96-46e9-9214-0e07ca61f6d5 devid 1 transid 11562 /dev/loop2 [ 379.511476] btrfs: disk space caching is enabled [ 382.959164] ------------[ cut here ]------------ [ 382.959192] kernel BUG at fs/btrfs/free-space-cache.c:1327!

Is the filesystem ruined or is there still hope, I can recover from that? Since YaST makes a snapshot before the update, my original plan was to revert to that I tried some subvolid values, btrfsck reported and they had the same kernel BUG as without one or even 0. Here are some hopefully useful outputs. If you need any more, I made an image of the partition so I can still debug it even if I re-install. ------------------------------------------ # btrfs filesystem show failed to read /dev/sr0 Label:
