Hi
My computer froze and I had to power-cycle the PC. After reboot,
attempting to mount the btrfs volume leads to a kernel oops:

Hi
Doing a btrfsck and then mounting with -o recovery finally worked. All

The crash actually happened on kernel 3.8 (Ubuntu 13.04) but I had to fall
back to a Ubuntu 12.04 LTS with kernel 3.2 to get it fixed.
Hope that Ubuntu back-ports btrfs bug-fixes into their LTS kernel - do they?
