Hello Tamas,
I think it would help to provide more information than what you have posted. "open_ctree" can cover a lot of territory.
1) I may be missing something, but I see no attachment. I am not sure the mailing list can handle attachments?
Indeed, thanks!

2) I think it would help to include some sort of brief narrative as to what you are trying to do when you encounter the open_ctree failure.
I'm just trying to mount the partition:
mount -t btrfs /dev/sda4 /1
dmesg after -o recovery:

super-recover says supers are good, btrfs-find-tree finds tree root, but chunk-recover fails.
Please post the result from smartctl -x <dev>
I'd make sure you're on kernel 3.14 at the oldest, and same for btrfs-progs. Currently you're on v.3.12. And then also post the result of btrfs check (without --repair).
smartctl -x:
http://pastebin.com/raw.php?i=S3eaCb8b
The machine was running 3.15rcX, when it failed. Unfortunately I have
only a live system now with this kernel versionI. I tried with the
latest btrfs-progs from git with no success.
btrfs check (with v3.12):
Check tree block failed, want=325877760, have=0
