I now repeated this on 3.4.4. Merely running a "btrfs scrub start /" causes this after a couple of minutes of running. This time I didn't run "btrfs scrub status /" in a loop, so that's not the cause. And judging from the two tries and two crashes, this seems very repeatable. The backtrace is basically exactly the same as with 3.4.4.
