Hi,

I was wondering if you could verify that you are seeing this bug on your Ryzen systems over there.

Wendell’s posted in this thread about it already:

Fyi -- bunch of people on Gentoo forum running into non-reproducible segfaults w/ Ryzen CPUs

I have been messing around with this today on my 1800x (retail) 1700 (retail) and 1600x (loaner from msi, thanks guys) I can cause segfaults all day long with the phoronix test suite but they seem to be in conftest? e.g. not real? with the same image, on x299 I get the same segfaults in conftest. I have experienced that I’ve had to up my SoC voltage a bit with memory overclocks/xmp but I hvae been testing at purely stock settings today. Testing on ASRock Taichi X370. Testing on Fedora 26 only. I am tempted to live boot ubuntu and see if I can get it to segfault. I am getting segfaults so I had a bit of a freakout… but then I realized its just conftest? so I think there is something to thise but the signal to noise ratio is too close to 1 for my liking at the moment?
