Bug 6192

When running the high quality Dragothic demo from 3D Mark 2001SE in Wine  
0.9.9, the system locks up hard before the demo starts, but after the loading  
screen fades away (ie, at the black screen between the two). I cannot ssh into  
the system, it will hang indefinitely before asking for my password (but will  
not time out). Attempting to switch VTs or kill the X server with  
Ctrl+Alt+Backspace does nothing. If I was already sshed into the machine and  
running top before running the demo, top will continue to run and display Wine  
using up 100% CPU time. After exiting top, I will be returned to the bash  
prompt, but cannot execute any programs, as it will hang indefinitely after  
attempting to run one, much like when trying to login via ssh. The system must  
be powered off manually and then powered back on again before it can be used  
again.  
  
I suspect this to be a bug in the radeon driver and not Wine as it should not  
be possible for Wine (or any user process) to hard lock the system.  
Furthermore, this crash does not appear to happen with other video cards  
(NVidia cards at least).  
 
To reproduce: 
- run the standard benchmark test in 3D Mark 2001SE using Wine 0.9.9 
 
Note that skipping directly to the high quality Dragothic test also produces 
the same crash. 
 
3D Mark 2001 can be found here: http://madonion.com/download/?3dmark2001.shtml 
 
Also, very recent versions of Wine do not install 3D Mark 2001 correctly, you 
will need to use an older version (something around 0.9.3 should work), or 
copy the files over from a Windows install. 
  
Using:  
- Radeon 7500  
- DRI CVS snapshot from 20051223 (installed through Portage)  
- Xorg 6.9
