Hello.
New test:
I booted from a live USB-stick with all updates installed
(4.4.0-21-generic), and after mount of the btrfs filesystem, the
balance continued, and a bug appeared in kern.log.
The filesystem turned readonly
An important directory was missing.

The corrupt from kernel message is quite dangerous.
I would assume there is some thing wrong with that device.
Maybe that's the problem leading to the BUG_ON.
And I also found that in your initial report, your extent tree seems to
be already corrupted.
Just as Chris said, it's a good idea to see how btrfsck complains about
your fs.
I assume it's already heavily corrupted though.
Thanks,
Qu

several times, and it happened every time again

Linux wolfgang 4.2.0-35-generic #40-Ubuntu SMP Tue Mar 15 22:15:45 UTC

What can I do to repair this problem?
The usual starting advice would be "try with latest kernel and see if
you can still reproduce the problem". Is it ubuntu wily? It'd go end
of in July anyway, so you might want to upgrade to xenial (or at
least, just the kernel, for the purpose of troubleshooting your
problem).
Or even try http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
(should be usable, but might report some errors/warning due to missing
ubuntu patches)
