This issue was successfully reproduced with the Cosmic kernel in -updates. Not 100% reproducible but this is what I did:
First successful attempt 1. Watch the syslog on SUT, run the ubuntu_cts_kernel on the SUT 2. Wait for a while, and this issue occurs (unfortunately I can't get the log, the initial error message got flushed away with the following destroy_worker+0x58/0x70 messages) Second successful attempt: 1. Watch the syslog on SUT, run the ubuntu_cts_kernel on the SUT 2. Wait for a while 3. SSH to SUT It looks like when the systemd kicks in, this will happen. Please refer to the attachment for the syslog output in this attempt. ** Attachment added: "cosmic-update.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813244/+attachment/5232454/+files/cosmic-update.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813244 Title: systemd logrotate cause kernel trace "BUG: unable to handle kernel paging request at 6db23a14" on Cosmic i386 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
