Comment 28 for bug 860485

I'm getting the suspend issue as well, in spite of setting things to "don't suspend" - surprisingly, it suspended even while playing music - I'd set a playlist to listen to while doing some work away from the computer, and had things come to a halt after 30 minutes. Everything is up to date on my machine.
What's worst is that this is on my desktop, which was never really meant to suspend - the hardware's a bit older and the motherboard was fairly basic even at the time of purchase. Once it suspends, I've got about a 50% chance of a successful resume that doesn't require hitting the reset button.
