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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1775486 Title: Bionic boot kernel oopses on Power Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Bug description: I'm trying to deploy Bionic to a Power S822LC (8335-GTB). The install fails because the boot kernel throws some oopses and reboots the server in an endless loop. The system powers on. Petitboot loads and populates the boot options. The system PXE boots the ephemeral boot kernel and then OOPSes and reboots, starting the cycle over. The following is the most I could get from a SOL session but it does show where the panics begin and the reboot happens at the end. The dump is from an attempt via MAAS to deploy Xenial with the 4.15 edge kernel. I also tried Bionic using the default kernel and got the same issue. Next I tried Xenial with the 4.13 kernel (hwe-16.04) and that kernel successfully boots. So the issue seems localized to the 4.15 kernel.
