'not MAP_STACK' was printed from sys/arch/powerpc/powerpc/trap.c and that's all i got. i think i got lucky that the trap printed a message because now there is no log. it just hangs after printing 'using parent'. i got no idea of the macppc memory map at the moment. my understanding now is that the kernel crashes quite early ... during the initial processing of ofw. 'using parent' is in macppc/macppc/ofw_machdep.c when i have time i'd be comparing the disassembly of the lowlevel files from both gcc and clang. my knowledge of assembly though is not really good. yorosiku ~
