<pre>It's an inbalance in the power domain reference counts. Once we managed to get
there only a report will stop these.
We have a few other reports, but thus far no one has a good way to quickly
reproduce these. Which is what we need to be able to understand where that
refcount goes amiss - all the backtraces here are way past the point of the
failure unfortunately.
So if you could try to figure out what sequence is required to get there
(really needs some good luck I guess) that might help.</pre>
