Maybe it did not hang but tried to output to screen which you have
disabled with -nographic. Try adding -append "console=ttyPZ0" to see
further logs on serial. (Then also add -initrd with the root filesystem,
you can check in yaboot.conf.)

/dev/shm/qemu-9.0.0/build/qemu-system-ppc -m 512 -M mac99 -smp 2 -nographic -cdrom ~/finnix-ppc-110.iso -boot d -bios /dev/shm/openbios-qemu.elf -d unimp -kernel /mnt/test/boot/ppc/linux -append "console=ttyPZ0" -initrd /mnt/test/boot/ppc/initrd.xz

yeah, it prints a bit more but panics with -smp 2 like this:

I am not sure if unxz code in kernel tries to use multiple cpus or not, sadly this kern does not rint exact number of cpus it found

may be void ppc kernel will print more?

I also tried to add multiple cpu support in openbios qemu ppc arch like it was done for sparc, but sparc just dump cpus in / of device tree?

so same trick ofc failed because I do not really know forth so no idea where to put for() loop start :)

Void ppc kernel printed a bit more:

============

so, this one more explicitly SMP aware, good ...

Guess plan of attack is

1) fix openbios so it creates more cpu nodes

2) fix openpic (keylargo variant) so it reports more than 1 cpu

3) deal with bugs :)
