Not a power failure, but twice in the last 6 months I had a random
reboot that left me unable to mount my root btrfs partition until I
booted into a live CD to run 'btrfs check'.

I've been trying out using subvolumes instead of partitions, but next
reinstall I'm going back to ext4.

I suppose it's possible that it was the btrfs error that caused the
random reboot, not the other way around, but that's hardly better.
