[Bug 999910] Re: [IVB]12.04 64 bit System freezes (mouse, keyboard)

I'm getting the same effect, where system freezes, screen is completely blank, keyboard is not responding (for example, num lock key won't toggle or anything), and SSH and ping and any other services don't respond. Every time it happens it has been during idle time, and usually after several hours
