denis, For what it's worth. Ubuntu mate does not seem very . . ."complete" on any ARM platform right now. For instance, the Odroid XU4 which has 4 cores A15's and 4 cores A7 uses an armv7 kernel( 32 bit ). Where the A15 cores are actually 64bit cores I believe. Same for the RaspberryPI 3 , and odroid C2 which both use A53 processors that are also 64bit cores . . . and this is not only for Ubuntu. It for all Linux's as far as I can tell.
But the point I'm trying to make here is that Ubuntu mate is new, so give it some time, and these issues which may, or may not be kernel related. To settle down. So if you have to use Ubuntu, in your shoes. I'd stick with 14.04. But honestly I'd never use Ubuntu on this specific hardware anyhow . . . an odroid XU4 sure, but not a beaglebone.
