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
