Xorg 6.9.0 freezes on AMD64 system with nvidia 6200 GPU

[Robert Gilaard]

Ok, I noticed that it's NOT the application that hangs
but the Xorg server.

I just started mozilla and after a few moments of
browsing the screen freezes. However, I can still se
my mouse, but it doesn't react anymore on any action
and it also doesn't change it glyph when moving over
the apps. I then killed the mozilla app this time, but
with no result.
The mozilla app is gone from the process list, but on
the screen of my desktop it is still showing....

Look at the process list now (I am running a postgres
job on the system now):

last pid: 57081;  load averages:  2.00,  1.80,  1.61

Will check the man page of gdb now and look at that
xorg process.

Thanks
Robert
