For some months now I am experiencing lockups when I switched to the VTs,
or changed the video modes or if I tried to shutdown the Xserver.

So I applied the following patch, after looking the related radeon patch
and now I can switch to the VTs or change the videomode without lockups.
But when I press Ctrl+Alt+Delete, sometimes my machine will lockup before
kdm starts a new Xserver or it will lockup right away after my monitor
has received the signal from the new Xserver.

If I kill the kdm process and then restart it everything will be ok. (At
least when I tried it)

So can anyone please help?

This is the patch:
