Yep, the second, older image works as expected. However, the recent one does not and I have absolutely no clue why. > That's using no VGA, so possibly there's something wrong with the video > setup on real hardware: > > $ qemu-system-ppc64 -nographic -vga none -M mac99,via=pmu -smp 1 -m 2G -nic > user -drive > file=$HOME/debian-12.0.0-ppc64-NETINST-1.2023-06-18.iso,format=raw,media=cdrom > -boot d > > I'll try and find time to test it on my actual G5 next week when I'm in > the office. The video issue can usually be worked around by disabling mode-setting or passing other kernel options related to the video card. That's not the main problem here though. The problem is that the newer image doesn't boot and currently I don't know why because installing the exact same kernel later from the package manager into an installed system works yields a bootable system with the latest kernel. The installer images are built from the same kernel package which makes the whole thing even more confusing. I'm using debian-cd to build the installation images: > https://salsa.debian.org/images-team/debian-cd/ Adrian -- .''`.
