SR MBP chokes/freezes when getting back from being idle for a while?

[ravenvii]

Ever since I got the iPhone, if I left the iPhone in it's cradle overnight, when I wake up in the morning and move my mouse to turn the display on, my computer would freeze. No kernel panics or anything, just a freeze. I can move my mouse around, but that's it. Sometimes it doesn't even have the time to turn the display on before freezing, so I'll be looking at a blank screen (with the backlighting on, so it IS receiving some kind of signal). The only thing I could do is hold down the power button to force it to restart.

(Note that my MBP was not sleeping, it was idle. There is a difference)

What do you guys think is up?

I found that it's happening without the iPhone as well. And I can create the syndromes consistently now. It will either: 1) just have the screen blank, or 2) be completely frozen except the mouse, or 3) semi-functional, but beachballs on everything you try to do, until you're just stuck with a beachball until you hard reboot.

Anyone had this strange problem? Is RAM a possible suspect? Any way I can test this?
