It looks like we should be able to perform a "Reverse" bisect to find the commit that fixes this in 4.17. We first need to identify the last bad kernel version and the first good one. Using your matrix in comment #4, can you test the following: v4.16-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16-rc1/ v4.16 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/ v4.17-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17-rc1/ Thanks in advance! ** Changed in: linux (Ubuntu Bionic) Status: Confirmed => In Progress ** Changed in: linux (Ubuntu) Status: Confirmed => In Progress ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775486 Title: Bionic boot kernel oopses on Power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Joseph, I couldn't exactly reproduce this as it happens during deployment. BUT the closest I could get was deploying 16.04.4 (4.13) and then installing 4.17 once I was up and running. So I did that, and I am able to reboot the system into 4.17: ubuntu@fesenkov:~$ uname -a Linux fesenkov 4.17.0-041700-generic #201806041953 SMP Mon Jun 4 20:33:53 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux ubuntu@fesenkov:~$ Next I installed linux-image-generic from Cosmic which got me a combination of 16.04.4 with 4.15 (4.15.0-22) and that is not bootable due to the OOPses that lead me to this bug. So this is the matrix of what's been tested: 16.04.4 - 4.13 - Success 16.04.4 - 4.15 - Fail 16.04.4 - 4.17 - Success So 16.04.5 and 18.04(.1) are broken on this system. ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775486 Title: Bionic boot kernel oopses on Power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Unable to log collect as this happens in the ephemeral during boot and the system is not usable. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775486 Title: Bionic boot kernel oopses on Power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
