Steps to Reproduce:
======================
 

1) Install Phoronix-test-suite version 1.8.1 from http://www.phoronix-   test-suite.com/download.php?file=phoronix-test-suite-1.8.1
   a) untar the phoronix-test-suie
   b) #cd phoronix-test-suite
   c) #sh install.sh

2)  Install test 
   #phoronix-test-suite install video-extensions

3) #phoronix-test-suite run video-extensions


Observation:
============

System hard hangs on application launch.

Additional Info : 
1) The problem is specific to R6xx. The OpenGL application runs fine with 
   R5xx series cards.
2) For some OpenGL applications (example: norsetto-shadow), the application just fails to launch
3) glxgears crashes with the following message :  drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.

You need kernel 2.6.32 for 3D support on r6xx/r7xx chips.

The issue is the output of "glxinfo" ( "direct rendering: Yes" &&  "OpenGL Vendor string: Advance Micro Devices,INC.") is misleading to the end user if 3D support is not there for kernel version 2.6.31 and R6xx . 

It should clearly say  direct rendering: No or Software rasterizer instead of hard hanging the end user system.

fixed with the latest kernel 2.6.32-21 and ddx xf86-video-ati-6.13.0
