error in intel_display.c causes blank screen

[svenmeier]

Sometimes on my Lenovo Yoga 2 the screen is turned off every 10 seconds. Note that this happens even when I actively use the machine, I don't have to leave it idle.

If I then enter some input (via touchpad or keyboard) or when I wait for another 10 seconds the screen turns on again.
I'm experiencing this problem since switching to Ubuntu Gnome 15.10. Sometimes I can fix it by rebooting the system, but the problem reappears after a few days; sometimes the problem disappears by itself.

All power settings are changed to never dim screen brightness or blank the screen. The notebook is connected to the power supply.

Note that I have two identical notebooks, so I'm sure it's not a hardware problem.

I'm wondering why "intel_runtime_suspend" is occuring in the log, when I actually didn't suspend my machine.

[Hajo Passon (hajo-passon-b)]

On a Lenovo G70-70 I encounter nearly the same problem. Sometimes the laptop enters a state where the screen gets black every 12-13 seconds. Sometimes a suspend (close/open lid) helps, often it does not. Sometimes the system recovers without any intervention.

I'm running kernel 4.2 for two weeks now and the problem in intel_display.c did not show up any more.
