I'm using the 32 bit beta, and the same thing seems to be happening to me. Very random. I have tried ctrl-alt-F2 to jump out, alt-f1,(mouse might be able to still move around) and even alt-sysrq+ REISUB (mouse is locked also afterwards) with no effect. Computer is locked up, must hard reboot. Let me know if I can tell you anything else.
