Title:
  btrfs balance crashes Ubuntu 12.10 when online changing raid level

Status in btrfs-tools package in Ubuntu:
  Fix Released

Bug description:
  No matter if I change the btrfs raid level to 0 or 1 Ubuntu 12.10
  crashes. The screen is frozen and btrfs balance stopped. After turning
  off and on btrfs continues the balance job without any further crashes
  or errors.

  What I have: btrfs with @, @home, @opt, @var all mounted respectively

  What I do:

  sudo btrfs balance start -dconvert=raid0 -mconvert=raid1 /
  or
  sudo btrfs balance start -dconvert=raid1 -mconvert=raid1 /

  The crash happend once every time I changed the raid level on a root
  mounted btrfs. There is no /var/log/syslog or dmesg message about
  this.
