Replaced Kubuntu with LinuxMint 14.1 Cinnamon 64bit (see Mar. 4th). Because of Kubuntu’s update procedure which frequently seemed to hang around 57% (If I remember). However it did not really hang but seemed to be reading the disk drives (disk activity light on) I would come back over 10 minutes later and was still accessing disks. After awhile it would jump another 5%, then seemingly do the same thing. Wanted another KDE distribution so I downloaded/installed Linux Mint 14 KDE. Which did not show the same disk intensive activity.
