Public bug reported: Overnight I had 2 of 12 16.04 servers brick with the 108 kernel. They also do not work with 109. They work fine with 104. The other 10 worked fine on both 108 and 109.
All are hosted on VMWARE. The two broken ones stop at the same place. I was able to go back to the 104 kernel to get them working and pin the kernel version. Just for fun, I set zswap.enabled=0 and they both crashed with kthread starved for jiffies. They are both multi-processor with lots of ram and disk. I have a task from the Ubuntu Kernel team to try this with 'nopti'. I'll report back. ** Affects: linux (Ubuntu) Importance: High Status: Triaged ** Affects: linux (Ubuntu Xenial) Importance: High Status: Triaged ** Tags: pti ** Attachment added: "vmware console" https://bugs.launchpad.net/bugs/1742502/+attachment/5034568/+files/stuckkernel.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742502 Title: 108 and 109 kernel hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
