it's a really tricky problem because it seems to depend on how the kernel image is booted. It fails when trying to boot the kernel off the installation CD, i.e. like from here: > https://cdimage.debian.org/cdimage/ports/snapshots/2024-02-25/debian-12.0.0-ppc64-NETINST-1.iso but the kernel will boot fine when installing in an existing system which was installed with an installation CD which uses an older kernel. > https://cdimage.debian.org/cdimage/ports/snapshots/2023-06-18/debian-12.0.0-ppc64-NETINST-1.iso I have not really figured out yet what the problem is.
