I have a machine that no longer boots in a headless manner with -rc5.
It's an Celeron based NUC device. I blacklisted the i915 driver and
it boots fine, then I ran insmod manually and got the backtrace below.
This machine only has HDMI output on it. If I have it connected (even
if the monitor is set to display some other input) it will boot fine,
but the backtrace is still present. I'm going to guess the machine
"hangs" in headless because X causes some further issues in the
headless case.

Linux v4.0-rc4-199-gb314acaccd7e gets this splat in the headless state:

[i915]()
[ +0.000002] WARN_ON(obj->frontbuffer_bits)

which is what I thought one of these commits was supposed to fix. I
don't see that in -rc5, but then we have these other issues.
