I really wish I'd been fast enough to get all of this on video. You'll just have to take my word for it though...
So in the process of doing certification testing for Natty on the Edge 11, the machine just completely wigged out.
First, the screen turned almost solid white... but not instantly... gradually, it just faded into white. Then it turned black, wtih a frozen but very visible mouse pointer.
I could do nothing at this point, so I dropped to a shell.
But then the shell kept flashing. Not just flashing visibly, but as though it was being turned on and off. As long as I could see the text, I could type, but when the text disappeared, I was unable to type anything, and no keystrokes were buffered.
So I had to type some sample commands one char at a time, every time the text returned.
See the attached video to see the text going all <blink> on me.

Here's a brief video of some of the weirdness... it's in mov, sorry, that's what my camera shoots.
