--- Comment #4 from Rico kgbricola@web.de 2013-04-03 13:25:50 CDT --- Does it also freeze with the open source graphics driver?
Whats your kernel version and x version? Please have a look here http://wiki.cchtml.com/index.php/Hardware , the driver seems to be pretty picky about some dependency.
If the x server hangs, it's a driver bug. A normal app (as wine) is not able to crash / hang a correctly working system.
