I added a reference to this bug to the ISO tracker, however I currently can't reproduce it. Booting the installer ISO on a POWER8 machine with:
qemu-img create -f raw disk2.img 8G kvm -m 1024 -boot d -cdrom eoan-server-ppc64el.iso -drive file=disk.img,if=virtio or with: kvm -m 1024 -boot d -cdrom eoan-server-ppc64el.iso -drive file=disk.img just works. The boot with if=virtio briefly shows this kernel message before the d-i actually starts: vio vio: uevent: failed to send synthetic uevent but after a short while I get to the installer, and I'm able to install. This is tested with: $ bsdtar -x -f eoan-server-ppc64el.iso -O .disk/info Ubuntu-Server 19.10 "Eoan Ermine" - Beta ppc64el (20190926) but 20190926.1 does not seem to behave differently. I'm very willing to expand the tests cases to catch this issue, however I first need to be able to reproduce it. Do you already have a reproducer? -- 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/1845572 Title: udevadm trigger will fail when trying to add /sys/devices/vio/ Status in linux package in Ubuntu: In Progress Bug description: [Impact] This will cause the installer to exit early, causing a kernel panic before any prompt to the user. This is restricted to some Power systems. [Test case] A build vmlinux was used to boot the installer, and a prompt was available. 'add' was written to /sys/devices/vio/uevent was written to, and no error was found. 'add' was written to /sys/devices/vio/*/uevent, and modalias information was found when 'udevadm monitor -p' was run in the background. [Regression potential] Events may be missing and coldplug/hotplug of vio devices may fail. That was tested in the test case and not found to be the case.
