Hi Team:

I work for AAEON an Asus company who makes embedded, long life, motherboards. I 
am running into a situation with a large customer of mine that wants to use a 
15.6" LCD Panel, 
https://dl.dropboxusercontent.com/u/52392/TFT-LCD%2BPreliminary%2BSpecification%2BG156BGE-L01%2Bver%2B1.0.pdf
  connected to the EMB-BT1 with the n2807 SOC, I have also tried the 
E3825/E3845 series and have the same issue, 
https://dl.dropboxusercontent.com/u/52392/EMB-BT1.pdf connected via the LVDS 
Connector. AAEON takes the eDP port and runs it through a Chrontel CH7511, 
http://www.chrontel.com/media/Datasheets/CH7511B%20Brief%20Datasheet%20V1.13.pdf
 chip to convert it to the LVDS Signal.

The issue I am having is when LVDS is only connected and the system boots up I 
do not get a picture on the LCD Panel. Once I kill power to the board and 
connect a HDMI or VGA connection the board boots up with Ubuntu 14.04. I am 
able to boot into the BIOS and check all the settings but once I leave the BIOS 
and Ubuntu tries to start up I get a white screen on the LCD Panel. Here is a 
video I took: https://dl.dropboxusercontent.com/u/52392/LVDS.mp4. I have been 
trying to load the daily and drm-intel-nightly builds of the latest kernel but 
this issue still comes up. I have even tried today's build of 2014-05-15.

I know this is something with the Linux Kernel because when I load up Windows 8 
I get a picture automatically every time without this white screen. I also have 
tried Timesys 18 Fedora Remix Image: 
https://dl.dropboxusercontent.com/u/52392/GettingStarted_Timesys18FedoraRemix.pdf
 and I do not experience this issue.

Please contact me if you have any questions or things to try. My contact is in
