Once you try to upgrade the system to ascii, the system will start to freeze after 30s on each boot and will stay idle. I freezed during first upgrade to ascii, but on my second try I managed to end the installation of ascii, and the same happened. It isn't a X related bug because on my second try, I hadn't even installed any DE. It isn't because of a faulty SD card because I tried on two different SD card or faulty computer because my Devuan Jessie works like a charm. I tried two times on my ASUS C201, thus it is a chromeveyron.

I guess it's linked to an incompatibility between an ascii package and the graphical driver. I'll try again but without the GPU driver.
