If the problem was illegal instruction, I would agree with you, but it's hard to see how the compiler that works with Intel and other AMD processors would case segmentation faults. In addition, the rather long thread I read indicated that the problem was erratic. Users would repeatedly compile mesa (or other packages) in a loop and it would fail at random iterations. That points to HW. My best guess that the problem is some sort of complex timing problem between the processor and it's support chips. -- Bruce -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

One thread starts at https://community.amd.com/thread/215773?start=0=0 and it looks as if segfaults are common. Other reports, e.g. at phoronix, note that some users are seeing the problems and others aren't. ĸen Thanks for the link, it's very enlightening. It seems that I'll have to delay the order until things clear up. A chasing game is happening between users, AMD people, bios manufacturers, and kernel and gcc developers, and I'd rather not get into that. Opting in favor of Intel's safety is still an option, but 8 cores, 16 threads, at 65w TDP, for about 300 euro is very tempting and I think it deserves some waiting. -- Thanos -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

Yeah, the issue has blown up over the last week or so, and there doesn't seem to be a lot of clarity yet... It's probably not helped by the fact that a lot of the reports are probably different problems - some might represent a genuine Ryzen problem, others could be bad RAM, others software bugs, etc... there are so many possible causes for segfaults.
