Public bug reported:
I get these frequent CPU core locks. I got this on current CPU AMD Ryzen 1700
as well as AMD FX-8350. All hardware has been switched out except HD. Same
issue. This seems to be a Kernal issue as far as i can tell. I started getting
this issue in Ubuntu 14.04 with and without proprietary drivers.
