I have the same problem with the 32 Bit version. Frequent random lockups, the only thing that will work is the mouse cursor, hard reset to recover. The problem has also occurred during normal shutdown and system hangs and needs to be powered off to shutdown. Have been forced to go back to Windows! 11.10 was working perfectly.
