I've had the same problems with Ubuntu 12.04 as well as Kubuntu 12.04. Screen would randomly freeze, particularly while watching a video. Pointer completely unable to move, and if audio is playing, it skips like a scratched record. At first I thought it might have been instability with the newest version of KDE, but when it happened with mainline Ubuntu, I realized that it was most likely the kernel.
