Again, working sha1 missing. Also, dmesg with drm.debug (only boot-up, so that we know about the hw) missing. And please attach xrandr --verbose output, thanks.

I check the git commit with log,the kernel which I test is the latest version. I attach the dmesg after booting with drm.debug=0xe.

This kernel is a good commit last time tested: Kernel: (drm-intel-testing)c3c3d4e9c2daeca01c42040cda0e5e0579c5c80b Some additional commit info: Merge: e04190e 99d0b1d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun Sep 9 12:07:07 2012 +0200
Hm, xrandr only shows HDMI3 connected, no DP port connected. Is this from the same machine/setup?
I've also looked at the relevant commits between good and bad sha1 and nothing popped out that could explain this. Can you please try to bisect this issue?
