[xf86-video-intel] Need help solving issue with intel driver & DDC monitor detection

[Jerone Young]

Sorry about that I have the bugzilla up now:

I miss understood your comment about ModeDebug..I created new logs

*Points of Interest*

Hotplug
======
So the hotplug log is interesting. I tried hot plugging 2 times and
both in the log it only prints out:

(II) intel(0): EDID for output TMDS-1

and not the rest of the EDID data.

 Have all files attached. Will post things in the bugzilla soon.
