For the record:

I saw the same message (incl. hard lockup) when doing a balance on a
single-disk btrfs.

Besides that, the fs works flawlessly (~60GB, usage: no snapshots, ~15
lxc containers, low-load databases, few mails, a couple of Web servers).

As this is a production machine, I rather rebooted the machine instead
of investigating but the error is reproducible if that would be of
great interest.

I used Debian Backports 4.2.6.
