Comment 10 for bug 1538741

I'm in the process of bisecting.

The latest kernel ( http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-rc7-wily/ ) is affected by a freeze, too. I'm not sure if it's the same as the one that I'm seeing in the 4.0.x series: On the latest kernel, the system simply freezes after trying to use it after the screen has blanked out. The original screen content is properly restored. In the 4.0.x series freeze, the the screen content shows a single color or a stripe pattern when the freeze happens.
