I'm having this same issue. After using computer a while, mouse and keyboard begin to hang for a while. After that mouse cursor usually begins to move - but doesn't react clicking. Keyboard seems to be all dead. Befor missed event texts I have in Xorg-log following which might be caused by this issue:
... (II) NVIDIA(0): Initialized GPU GART. (II) NVIDIA(0): Initialized GPU GART. (EE) NVIDIA(0): Error recovery failed.
