Ubuntu 16.04 edu-docker image not stable

Days ago I started using the edu-docker images. It was 2016-09-26-ubuntu-mate-16.04-Xenial-edu-docker-demo-bpi-m2u.img with 3.10.65 kernel. My m2u board went dead every day. After re-plugging power input, every thing was back to normal. I wonder whether any other people is in the same situation.

Is there any new images which support docker for m2u?
