Software environment:

Gentoo ~x86 
Kernel 2.6.36
xorg-server-1.9.1
xf86-video-intel-2.13.0
mesa-7.9
libdrm-2.4.22
cairo-1.10.0

To reproduce:

1) Start X-session and run MANY application (gvim, firefox, xdvi etc)
2) Work a litle bit 
3) Hibernate
4) Resume
5) If no effect - retry

In my case, the bug is usually unreproducible in the case of hibernate with more or less fresh x-session and 99% reproducible in the when I do some work 
during, e.g., 1 hour and do hibernate afterwards. The googleearth run when hibernate almost always leads to problems.


The character of screen corruption is different in dependence of xorg.conf options. 

General case is 

Section "Device"
        Identifier "Graphics Adapter 1"
        Driver     "intel"
        Option     "AccelMethod" "UXA" 
        Option      "Tiling"        "True"
EndSection

In this case I have some kinds of screen corruption (see screenshots). Sometimes the font corruption disappear after next hibernate cycle, but usually this does not help.

In the case 
        Option      "Tiling"        "False"
I never saw screen corruption. But instead of this after resume I obtain black screen on the corresponding console (where Xserver is run). This (black screen) cannot be fixed somehow, the only method to fix is to restart X-server.

Third case is Option "Shadow" "True". In this case I never saw the problems, but I did not investigate this case much.

Please, indicate what kind of additional info can I provide to fix this problem.
Thanks!
