Bug#619865: Intel i915 compatible and drm xorg problem

[Oscar Cassetti <oscar.getstring@gmail.com>]

Hello,

After updating to xserver-xorg-video-intel 2:2.14.0-4  I had the same
problem on debian  wheezy/sid
I experienced this problem both on kernel   2.6.35.2 and 2.6.38.2
See the logs below.

I fixed my system by removing the package xserver-xorg-video-intel and
compiling  from original source
xf86-video-intel-2.13.0 from Xorg project.

I would suggest to revert the changes since this is  a pretty serious bug.
