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.

I have not really figured out yet what the problem is.
