Bug#597992: xorg: System freezes "randomly" while in X

[Ferran Xarnach Rotllan <flixil@gmail.com>]

Package: xorg
Version: 1:7.5+7
Severity: important

Dear community,

The system freezes randomly while running X, using kde, gnome or xfce.
The keyboard and the mouse seem to stop responding, even though the light of th
the freeze the magic sysrq keys stop working.
The module that I usually used for the graphic card is radeon but it freezes al
freezes even using different debian kernels.
The graphic card is ati radeon xpress 200M on a compaq presario v2311US.

This is my first bug report and I don't know exactly what to append.
I will be glad to provide more information as requested.

Thanks
Ferran Xarnach Rotllan, flixil
