on comment #125 there is the /debug/dri/0/i915_error_state with 3.5.0-28 kernel, with this kernel compiz and unity crash immediately after the login and graphics quickly become corrupted, I didn't waited Xorg to be locked up as anyway it isn't possible to work with that kernel

with all these kernels I can kill Xorg and log into a console to grab /debug/dri/0/i915_error_state without need to do it with ssh from another pc
