I can retry with your version too, but I don't think it will make a difference.= The kernel works fine with gcc, but doesn't work compiled with clang. Booting [/boot/kernel/kernel]... jumping to kernel entry at 0xc0088000. OF_panic: sparc64_init: cannot find boot CPU node Program terminated {1} ok So, the same panic with your and dim's patch, compiled with clang. Userland was compiled with gcc, cc is gcc and I used "CC=3Dclang make kernel" to build the kernel with clang.
