Log from the X start.

On HP Compaq nx6325 notebook with Radeon Xpress 200M GPU, when a game based on quake3 engine (Quake III Arena, Enemy Territory, ...) is starting the X freezes and screen remains black. Keyboard stops responding; it is not possible to switch to the text console with Ctrl+Alt+Fn. After "keyboard reset" with magic sysrq key combination Alt+SysRq+r the keyboard becomes responsive (CapsLock switches the LED) but switch to the text console still does not work.

Login via ssh is possible and 'top' shows that the X process consumes 99% CPU. The game has to be killed with -9 signal so as the X. After killing both the game and the X, machine (display) remains unresponsive as before. Reboot is needed.

Using git version of the Mesa, libdrm, and xf86-video-ati. However same behaviour is with Mesa-7.5.1, libdrm-2.4.13 and xf86-video-ati-6.12.4.
Kernel versions were 2.6.32-rc8 and 2.6.30. Xorg server version is 1.6.3.901 (X11 version 7.4).

My xorg.conf is empty. Same behaviour also with "AIGLX" "off" and "Composite" "false" options.

All listing below and attached are from the newest versions (git and 2.6.32-rc8 kernel) and empty xorg.conf. Also they all are before the freeze. After the freeze I did not noticed any new related entries in logs.
