dmesg-2016-AUG-18.txt

I'm running drm-intel-nightly with modesetting driver to (hopefully) help
provide additional information, but this error has been occurring during boot
on this laptop for all kernels since at least 4.4.

I've tried searching for solutions, but most of them seem around problems with
having a monitor plugged in. However, I get this error 100% of the time while
booting *without* a monitor plugged in.

First time reporting a bug here, so please let me know how I can help with more
info - dmesg should be attached:

Linux cirdan 4.8.0-1-drm-intel-nightly #1 SMP PREEMPT Wed Aug 17 20:46:46 MDT
2016 x86_64 GNU/Linux
