Exactly the same thing is happening to me, it seems to be happening only with nvidia chipsets, as far as I've googled. It's a shame nobody seems to have any kind of help regarding this issue. It's most certainly not an overheating problem, my sensors tell me it's at about 70°C when crashing.

I'm doing the same thing now. Same error, GPU is a Geforce GTS 250, temperature is normal. What I noticed though is that it crashes right in the moment when my GPU load reaches 100% for the first time. If that is of any help.
