further to that, can you ssh into the box? Just because it doesn't
respond to the keyboard doesn't mean it inaccessible. 

And, use alt-sysrq-s to sync your disks before you power-down. you can
also alt-sysrq-b to reboot, if you don't want to go the power switch
route. If the kernel doesn't respond to the alt-sysrq keys, then
you've got a truly hard lockup and I'd start looking for hardware
