My guess: you have USB-attached storage that’s waking up when you wiggle the mouse, and it’s crashing the bus, kicking the kernel driver over, so the system reboots to protect itself. If not storage, then something else sufficiently complicated, which wakes up when you wake the system. I’d exclude things like optical drives, unless they have disks in them at the time this happens.
