To get a better hold of the actual bad instruction I installed Ubuntu 19.10 in a guest using the 3.1 based machine type. Then after the full install (much more capable than the busybox of the installer) I switched the machine type and booted up with the new machine type that also implies the power9 cpu.
With that it still boots up, but I've seen a few illegal instructions. On login I see /etc/update-motd.d/98-fsck-at-reboot, also apt install of gdb failed. In the journal I have found 8 more. I can't install anything, so it seems I need to switch back and forth between CPU types whenever I need anything on top ... But now (full install) fortunately the crash collection in /var/crash worked so I have a few dumps to check. With the older emulated CPU I then went into debugging these cases to check for a common pattern ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847806 Title: eoan: ppc64el install on pseries-eoan VM fails to install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1847806/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
