dmesg of the session with drm.debug=6

Hi

I'm using Debian Unstable, with current drm-intel-next kernel, Xorg 1.12.4-6,
current git xf86-video-intel.

The laptop is X60S, with Intel L2400 Core CPU. 

My desktop environment is XFCE 4.8.3, which probably triggers suspend on laptop
lid close.

When I suspend the laptop like this, on resume I first see a black, powered off
screen, and when I press a key, the backlight turns on but the screen is still
black. I can VT switch to console. Switching back to X doesn't help. I can
restart my lightdm and X will start again normally.

When I suspend the laptop with suspend option on the XFCE logout screen, it
resumes normally. 

I've attached dmesg with drm.debug=6 and Xorg.log from the session that failed.

If you need more  information, please ask
