My main computer has been a bit unstable lately, after the last crash it wouldn't boot.

My root fs is btrfs on luks on an ssd. During boot, I get to type in my passphrase and then it just hangs a few lines after I short while after I have pressed enter. I tried booting off a usb-stick (on it now) and running fsck.btrfs on the filesystem, that caused fsck to crash, giving the error message here.

If I try to mount the btrfs volume, the computer will freeze.

It found some broken blocks:
bad block 19164823552
bad block 163270656
...
...

and then the last messages on the terminal were:

failed to find block number 6337802240
Aborted (core dumped)

I'm not sure whether my error is the same or not:

$ fsck.btrfs /dev/sda3
couldn't open because of unsupported option features (8).
fsck.btrfs: disk-io.c:679: open_ctree_fd: Assertion `!(1)' failed.
zsh: abort (core dumped) fsck.btrfs /dev/sda3

My system does not freeze and I can mount the device with no problem.
The partition is on an SSD, system is an uptodate Precise:
3.2.0-19-generic
btrfs-tools 0.19+20100601-3ubuntu3

I think, this is a serious error.
