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?
