I wish AMD hadn't decimated their Linux team (several years ago), and they definitely had some embarrassing issues early on with Zen (apart from the Zen 1 stability issues, they've screwed up rdrand at least three times, iirc). But I've yet to hear of any Zen 3 issues, and I suspect I'll upgrade when Threadripper comes out (I've become quite spoiled by the build speeds of my Threadripper 3970X - the only thing I miss is the better 'perf' support from Intel PEBS). Note that I'm not necessarily the person who would hear about any issues first, though, so take the above with a pinch of salt. Linus
