I think there is another bug report very similar to this one, but can't find it for now. I've never been able to use the stock ubuntu 16.04 kernel with my system (00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D]) and need to compile a patched kernel each time... Here are the 2 patches that resolve the problem for me.
