Description of problem:
When booting Fedora 17 from a 3.5.x kernel video stops working after early boot kernel output. Working fine with 3.4.x kernels

Version-Release number of selected component (if applicable): 3.5.x


How reproducible:
With 3.5.x kernel on this hardware: always
With 3.4.x kernel on same hardware: never

Steps to Reproduce:
1. Boot Fedora 17 (selected from grub2)
2. wait until display gets blank


Actual results:
After selecting the 3.5.x kernel from grub2, the screen goes blank. Then the Kernel prints some early boot messages (in 640x480 pixels or so) as expected. After some seconds and more output the screen goes blank and powers off (energy saving mode).

Expected results:
After the screen goes blank it should display the output again with full display resolution (the part where plymouth should take over). Then the HDD encryption prompt (luks for LVM2) should be displayed. After that it should boot to GDM. This is the exact behaviour you can see with 3.3.x and 3.4.x kernels.


Additional info:

1. If typing in the HDD encryption password blindly Fedora continues booting without any further problems but still with a blank screen. I can switch to TTYs and run commands, create files, use pipes to save e.g. dmesg, ….

2. Some basic hardware information:
CPU: Intel Core i5 650 with iGPU (in use)
Mainboard: Asus P7H55-M/USB3
Monitor: Some BenQ via HDMI, 1920x1080 resolution

3. Removing terminal_output=gfxterm does not fix this bug.

4. This bug may or may not be related to ID 852826 or 845388
