A comment on 50+ Segmentation Faults per Hour: Continuing to Stress Ryzen.

Note that it appears that a large number of the segfaults which Michael (phoronix) is reporting may be coming from a software issue. In particular, people on the phoronix forums are reporting that conftest segfaults are a known software issue and also one has reported that he was able to reproduce the conftest segfaults on an intel CPU.

So not saying that there's not a problem with Ryzen, but it is possible a large number of the errors are false positives arising from a known software issue.

I would wait Michael runs the same test on an Intel CPU with no problems to pass judgement.

Agreed. It is a very basic comparison, which should be done before posting the article. I don't understand why he keeps posting these before running the exact same test on different processors (an Intel or even a different AMD should be ok)

Phoronix likes the clicks?

It may not even be a software issue. conftest is the name autoconf uses for various short snippets of code used to test properties of the toolchain and host system, and if I recall correctly some of them generate code that's expected to segfault when run if some guess about the host system is wrong.

This isn't the case. I see segfaults in multiple tests with Ryzen and none of them are conftest related. The CPU is broken.

I don't have Threadripper or Epyc to test.
