I experience random lockups of the screen. The screen goes black then sometimes the image is back but frozen, sometimes it stays black. I can't do anything but a hard reset. It happens randomly when using KDE4 desktop and common applications (eclipse, firefox etc.). I did not notice any correlation with any particular usage pattern or application. I have DPM enabled. I attach the significant part of journaclt log recovered after reboot.
