Public bug reported: There is a grave problem with the intel graphics driver in the karmic koala release. Since karmic was installed, the driver crashes every few days (with jaunty it was running perfectly stable). The machine itself remains up and running, but the display is turned permanently off so the only possibility I see is a remote login to reboot.
In dmesg I found this: Nov 11 17:07:10 zweistein kernel: [25202.184012] INFO: task i915/1:298 blocked for more than 120 seconds.
