It seems like I experienced a similiar error with Ubuntu 17.04 (with i5 3400 and RX 480). I wanted to re-login after the screen was locked. For more than a minute, I could not move the mouse nor switch from x environment to terminal or something like this. After some time, everything just worked fine again.

First, the following appears some times:

and than a similiar error occured:
