Not sure which package this should be against; since it might be DRM, maybe it should be against the linux kernel?

Status in xserver-xorg-video-intel package in Ubuntu: New Bug description: After a recent update (early Nov 2016), my 16.04 system (an HP Pavillion 500-321, i.e. a generic i5-4570 system with integrated graphics) started showing a black screen on boot (after the grub menu finished). A fresh 16.10 live USB image also has the same problem on this system (but not on an nvidia system), as does a fresh 16.10 install. A fresh 16.04 install does NOT have the problem; the problem can be reproduced on this system by doing a fresh 16.04 install followed by letting it update automatically to the latest 16.04 packages. After some experimentation, I discovered that after booting up into the black screen, I could (usually?) rescue the session by pressing the computer's power button. This brought the screen to life, showing Ubuntu's "reboot or power down?" dialog. Cancelling that left you with a working system. I also discovered that if I booted first to text mode with sudo systemctl set-default multi-user.target and then after logging in via text mode, switch to graphics with startx or with sudo systemctl start graphical.target the screen also was fine. So, um, er, is it a race condition? Is graphical.target missing a wants? And what recent update could be introducing this problem?
