AMD has performance problems with AMD Ryzen processors in heavy loads under Linux and the company is working on solving it, in addition, it has already said that this problem will not be in the Threadripper and the EPYC.
A performance issue has been detected in AMD Ryzen processors on certain workloads under the Linux operating system, causing major flaws in the segmentation of continuous, highly heavy workloads on Ryzen silicon. This issue occurs under parallel build workloads specifically, which has been confirmed by AMD. This has been detected thanks to Phoronix, who have put AMD processors to the test, which in the face of stress tests, these processors have failed with multiple segmentation problems.
It is true that this problem occurs easily in highly heavy workloads, but that it does not exist in common Linux tasks and in benchmarks. AMD on the other hand, wanted to clarify that this problem does not appear in the EPYC and Threadripper processors, which as we know, are designed for the industrial and professional segment, respectively, where people work a lot under Linux. They wanted to clarify that this happens only in the first Ryzen and that under Windows this important performance problem does not occur.
AMD has also wanted to specify that the segmentation failures of the Ryzen are not isolated in a specific motherboard manufacturer, but are due to the processors themselves. The company has already said that those who have problems with these Ryzen, contact the AMD Customer Service, to solve the problem. Customers have already contacted the company for thermal, power, or other issues, and AMD has committed to working with them to address performance issues under Linux. AMD has also said to intensify testing under Linux, to avoid quality and performance problems in the future.

I measure it as a big problem because these cpus are quite used as servers and almost all are linux because windows server is not very good
It is not a problem because it is in Ryzen, in Threadripper and in EPYC this problem is not occurring.
I quote: "It is true that this problem occurs easily in loads of
heavy duty work, but it does not exist in usual tasks of
Linux and benchmark. »
I am planning to buy the r5 1600 to use it in a leisure environment (video games port AAA) and development (of applications in parallel due to its 12 threads) under linux, can I find this kind of problem?
"Ryzen segmentation faults aren't isolated to a particular motherboard vendor or the like, contrary to rumors/noise online due to the complexity of the problem"
I mean, the problem is given to a motherboard, from one of its vendors. It sounds more logical to me, since if not it would be in all the processor lines, therefore it leads me to an errata of BIos than of CPU.
I am not an expert in linux but this problem may be due to the ryzen architecture, the bios or the kernel that is not yet fully compatible with ryzen
