Hi Brice,

No, the whole machine is freezing (above, the ssh session is not responding 
anymore) and I have to hard reboot.

I try the 6.7.197 unstable package and the problem persists.

There's no log! :,(

If I erase /var/log/Xorg.0.log, start gdm, [freeze], hard reboot in console: 
no /var/log/Xorg.0.log is created.

The same if I do a "startx 2>log" in console: nothing in log.

I tried with the -dbg package installed but with no more results. Is there 
anything to do to enable the "debug feature"?

I suspect the changes in the AGP code is responsible of this bug. I will try 
to get the git version before the change - I'll have to learn how 
before ;-) - to see if it works.

Sincerely, 

Yannick
