Title:
  dirty reboot always results in unbootable system if root is btrfs

Status in btrfs-tools package in Ubuntu:
  Confirmed

Bug description:
  Probably it is not a btrfs-tool bug but it is a btrfs related one.
  I'm using btrfs as my rootfs in 15.04. Whenever I do a dirty reboot (power outage, sysrq-reboot, etc...) ubuntu is not bootable anymore. Ubuntu splash is kept in loop forever but Ctrl+alt+del works. The only workaround I found is to reboot in a livecd and do a 

  btrfs check --repair /dev/sda6 (my rootfs)

  Which seems to undo part of what was changed in fs (including logs).

  Is there any better way to debug this?
