dmesg, xrandr, vbios, intel reg dump

This bug is still reproducing on my machine:
Distro: Ubuntu 16.04
CPU: Intel(R) Core(TM) i7-6700K
MB: Asus Z170-A
kernel: affb4fed39e6ec65cd44f102624885bc97fbfd70 drm-intel-nightly:
2016y-02m-04d-09h-08m-18s UTC integration manifest

This is reproducing always on boot only when I have 2 monitors (both HP
EliteDisplay E241i) and only if one of them has a DP connector.
