Bug Description
Release: Linux Mint 15 "olivia"
Edition: Cinnamon 64-bit
$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation G72M [GeForce Go 7400] (rev a1)
Totally random freeze, mouse is moveable and able to enter console via ctrl+alt+f2. If I wait a few minutes sometimes longer, it works normal again but will freeze again randomly. To reproduce, just run any program and it will eventually hang at some point. It's impossible to work with nouveau driver because of this. This is what I got from kern.log:

I'm on Nvidia propriety driver now, but it's not as good as nouveau driver due to some blurry font here and there.
Search around at nouveau project and found some related/duplicate of this bug here:
