By updating mba6x_bl module this issue went away. I am unable to replicate it on 4.4.x as there are build issues (initial is with stack protection gcc flag which does not yet exists in trusty, then something about signing module).
Feel free to close this, as it gets resolved with module update.

If I reboot it with kernel -63, everything is back to normal. Any hints about this one?
