<pre>I have not yet been able to figure out why the packages on
<a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc3/">http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc3/</a> and my builds of those
same commits do not behave the same.
However, I started bisecting again from scratch, being careful to avoid taking
any shortcuts (such as assuming that I could skip a build because I had a
pre-built copy for the commit), and also being careful to do extra testing at
each step (it turns out there are other problems that occasionally produce
similar-looking symptoms, so I had to do extra testing to ensure that I was
consistently reproducing this specific issue).
I've now managed to successfully bisect the issue to commit
339fd36238dd3494bc4617d181e7a37922c29ee9.
Just to double check this, I also built v4.9-rc5, verified that it reliably
hangs when starting X, then reverted 339fd36238dd3494bc4617d181e7a37922c29ee9
and re-built v4.9-rc5, and verified that it reliably works correctly.</pre>
