This particular problem seems to panic on 598th line of
sys/arch/powerpc/oea/ofwoea_machdep.c:
   591  ofwoea_bus_space_init(void)
   592  {
   593          int error;
   594  
   595          error = ofwoea_map_space(RANGE_TYPE_ISA, RANGE_IO, -1,
   596              &genppc_isa_io_space_tag, "isa-ioport");
   597          if (error > 0)
   598                  panic("Could not map ISA IO");
   599          error = ofwoea_map_space(RANGE_TYPE_ISA, RANGE_MEM, -1,
   600              &genppc_isa_mem_space_tag, "isa-iomem");
   601          if (error > 0)
   602                  panic("Could not map ISA MEM");
   603  }

If you insert the following line on 594, output stays after start= line.
while (1) {};
