The attached test patch fixes a potential race in the kernel which might result in missing TLB flushes. In addition it adds a "notlblc" kernel parameter which allows to disable the local TLB clearing optimization. Note: this is just a test patch to verify if it solves the seen problem. This patch should currently not go into an official kernel release. @Canonical can you please build a test kernel which includes this patch? The patch is against kernel version 4.4.0-89.112. Thank you! ** Attachment added: "tlb test patch" https://bugs.launchpad.net/bugs/1708399/+attachment/4930602/+files/ubuntu-xenial-4.4.0-89.112-s390-tlb-test.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708399 Title: kernel panic -not syncing: Fatal exception: panic_on_oops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1708399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
