I've seen a couple crashes on a ThunderX CRB1S system - though at this point I don't have reason to believe it is related to KPTI. This system happened to be installed with LVM + crypted home, and we haven't ran the cert tests on such a config before. After the remaining tests complete, I plan to re-run with the pre-kpti kernel on this config, as well as running cert on the "usual" config w/ a kpti kernel. I was only able to capture the console of one of the crashes, I'll attach it here.
I also have a cert run still in-progress from a Gigabyte R120. This system is very similar to the CRB1S, and has not seen any problems yet. ** Attachment added: "thunderx panic console log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1749040/+attachment/5066573/+files/console.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749040 Title: KPTI support for arm64 systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1749040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
