xf86-video-intel 2.6.0 + kernel 2.6.28 == GTT full, but LRU list empty on AOpen MP45

[Vincent Mussard]

Hi

Intel 2008Q4 graphics package don't work on my AOpen MP45 (GM45 X4500HD).
I got no output from X and the driver seems to crash :

Backtrace:

15: /usr/bin/X [0x432a79]

In the same time, in the kernel trace I got :

[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty
[drm:i915_gem_object_pin] *ERROR* Failure to bind: 
-12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty
[drm:i915_gem_object_pin] *ERROR* Failure to bind: 
-12<3>[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty
[...] several times

I have no xorg.conf.

Using kernel 2.6.27 with all the same component (libdrm 2.4.4, 
xf86-video-intel 2.6.0 and mesa) all is working properly except I don't 
have 3D Accelleration :

[...]

Any hint or advice ?
Should I open a bug with more information ?

Thank you
