Public bug reported:

Binary package hint: xserver-xorg-video-intel

This is fresh install of Ubuntu 10.04 (64 bit) on Intel Core 5 on Intel board. The installation has not been changed, the X server is running without the xorg.conf file.
After some time suddenly the Xorg server hangs, mouse and keyboard (USB) completely hangs too. But the system is available using SSH. The kernel logs:
