I am also having random freezes when opening a second display, doing some
work on it, and closing the display. Not fully reproducible, seems that just
opening and closing did not (yet) trigger the problem. Only once my main
display got frozen. Cannot even switch to other display when this happens.

Just wanted to add that I can recover control with the Magic SysRq+k, that
allows me switch to other display and resume work in it. After sysrq+k and
before switching display looks frozen, but allows me switching. Some
rubbish appears in the old display after switching back.

So at least here, seems to not be a full machine lock up, I am sending this
mail after that.

VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 SE] (rev01)
xserver-xorg-video-ati 1:6.8.0-1 (I think this happened with .197 too)

The problem does not appear with testing (1:6.6.3-2)

Hope this helps,
