This morning I was on a call with AMD and they are now able to confirm they have reproduced the Ryzen “segmentation fault issue” and are working with affected customers.

AMD engineers found the problem to be very complex and characterize it as a performance marginality problem exclusive to certain workloads on Linux. The problem may also affect other Unix-like operating systems such as FreeBSD, but testing is ongoing for this complex problem and is not related to the recently talked about FreeBSD guard page issue attributed to Ryzen. AMD’s testing of this issue under Windows hasn’t uncovered problematic behavior.

I give AMD credit an issue was brought to their attention and they are addressing it great customer service.
