It seems to be confirmed as a hardware problem. See: https://www.phoronix.com/scan.php?page=news_item&px=Ryzen-Segv-Response
I have entered in contact with AMD and am doing an RMA of my CPU in the next days. From what I could grasp the bug is usual in the first batches of Ryzen, so there might be many affected CPUs in the wild. AMD is not issuing a recall, it will treat with it in a case by case basis. Anyone can check if their CPU has the problem by running the kill- ryzen.sh script described in the original bug report. If your CPU has the problem contact AMD technical support using the link in the Phoronix article linked above. Maybe I should mark this bug as invalid? At least the bug report will remain here so that other affected Ubuntu users may find out how to proceed. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708222 Title: Long, multi-threaded compilations, segfault in Ryzen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1708222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
