We did have another revert to fix hopefullythe last "blank screen" regression on intel graphics.
It seems that there is still a regression for intel graphic cards backlight. One report is https://bugzilla.kernel.org/show_bug.cgi?id=22672. I can reproduce the problem easily by: xset dpms force standby; sleep 3s; xset dpms force on
(You are using "vesa" or "fbcon" X11 driver, right? I seen same problem until I switched to "intel" X11 driver).
