[Samsung Galaxy Nexus] rogersnm:
I set display timeout to 10 minutes, CPU to 192-1536 (wheatley) with SR on and 1400 mV max voltage and got two reboots. The first occurred with screen off whilst connected via usb (fastcharge mode), the second occurred whilst not connected to usb with screen on idling on the home screen.

Compare those to a reset with 1350 mV max voltage (too few volts) on the interactive governor:
