Bisection blames this one:

address@hidden (1):
      target-ppc: optimize cmp translation

A plain boot doesn't work either:
./build/ppc/ppc64-softmmu/qemu-system-ppc64 -display none -serial stdio

so you can see it's already diverged because it prints out
a different value for the name of the pci node and the
SCSI line has 8200000000000000 vs 00000000.

(This is a build for arm32, running in a chroot on an aarch64
box, non-debug build.)
