Subject: btrfs unmountable: read block failed check_tree_block; Couldn't read tree root

Hi!
My btrfs system partition went readonly. After reboot it doesnt mount
anymore. System was openSUSE 13.1 Tumbleweed (kernel 3.17.??). Now I'm
on openSUSE 13.2-RC1 rescue (kernel 3.16.3). I dumped (dd) the whole 250
GB SSD to some USB file and tried some btrfs tools on another copy per
loopback device. But everything failed with:
kernel: BTRFS: failed to read tree root on dm-2
See http://pastebin.com/raw.php?i=dPnU6nzg.
Any hints where to go from here?
Ciao
Ansgar
