When running the testing repo, Kernel 4.9.0 and 4.9.1 give me this error:

My CPU is an AMD FX-8350, but it appears to affect other distributions and other AMD CPUs, so it's highly likely an upstream AMD issue.

I just thought I would let you all know in case there is a patch that can be pulled in before this is sent to stable
This task depends upon
