[Intel-gfx] Xorg freezes with recent xorg-server/ xf86-video-intel

[Stephan Raue]

Hi all,

i use Xorg in on an embedded like linux distribution to start XBMC as 
the only application. XBMC starts succesfull and i can use it some 
minutes. after some time Xorg freezes.

i have tryed:
- xorg-server-1.8.1, xorg-server-1.8.1.902, xorg-server-1.8.2, 
xorg-server 1.8.99.903
- xf86-video-intel 2.11.901, xf86-video-intel 2.12.0
- mesa-7.8.1, mesa-7.8.2
- libdrm-2.4.21

what can be wrong?

greetings

Stephan
