It was originally reported that Linux users were facing segmentation faults and, at times, crashes when running concurrent compilation loads on Ryzen CPUs, and these issues don't appear to be fixed: Phoronix has run additional tests and found that heavy workloads remain problematic, as of Linux 4.13. These problems did not occur when tested using Intel CPUs. We'll see now if AMD will provide public comments or if they investigate further, as they now have another reproducible test case to slam the Ryzen chips hard in just a few minutes even with SMT disabled and running at DDR4-2133. As far as whether this just affects Ryzen or also Threadripper and Epyc remains unclear. While there are many Windows reviewers out there now with Threadripper, it doesn't look like AMD will be sending any Threadripper samples to Phoronix, at least in the immediate days ahead but I have asked if at least can get SSH access to a TR system for a few hours to be able to run some Linux benchmarks. We'll see.
