Thanks for the report.

I do test qemu mac99 as part of my CI, and it's booting OK, so there
must be some config difference?

I'm using pmac32_defconfig plus:


And running with:

$ qemu-system-ppc -nographic -vga none -M mac99 -m 1G -kernel vmlinux -initrd $HOME/static/ppc32-initrd.gz -append "console=ttyPZ0 init=/bin/sh"
