I havn't any unordinary options in xorg.conf, but when I use some video usage my laptop Acer Extensa 4220 freezes. No Alt+PrntScr+O or any other key combination doesn't work. Mouse not move. This bug always happen, for example, when I run "qtdemo" --> "Graphics View" --> "Pad Navigation Example". Or sometimes happen, when I run glxgears. libdrm-intel1 version 2.4.5-0ubuntu4 xserver-xorg-video-intel version 2.6.3-0ubuntu9.2 I have Kubuntu 9.04, this bug had happens early (8.10, 8.04)
2D video is very slow, when using 3D system can suddenly hangup. > tail -n 500 /var/log/Xorg.0.log.old |grep VideoRam (==) intel(0): VideoRam: 262144 KB (WW) intel(0): Option "VideoRam" is not used xorg.conf is default.
Please attach the full Xorg.0.log and related dmesg output.
Created attachment 26020 [details] Xorg.0.log nothing special or unordinary. I didn't found any link to bug.
Created attachment 26021 [details] dmesg also, IMHO, nothing special

Can you reproduce the problem on a current system using KMS? We've fixed a ton of GPU hangs since then.
