I think that I have similar issue: On Kernel 4.18.0-16-generic I had: 1) Two unrecoverable freezes (sound looped, unable to SSH) 2) Random software crashes with segfault in dmesg 3) Random Chrome tab crashes with "trap invalid opcode" in dmesg
To reproduce segfaults I downloaded latest Kernel sources and make -j10 them (several times) to get some "realistic" load. Most of compilations failed with segfault. One ended with coomplete freeze and only one or two succeed. After booting with mainline 4.15.0-041500-generic from kernel.ubuntu.com I was able to compile kernel successfuly 3 times in a row. I have newly built PC with Ryzen 5 2600 and I am sure that my RAM is OK. Attached small parts of logs with segfaults and trap messages. ** Attachment added: "Logs" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798961/+attachment/5249729/+files/from_logs.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798961 Title: Random unrecoverable freezes on Ubuntu 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1798961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
