Been messing around with the O2 and KGDB and well, theres a problem that I don't quite know how to tackle, when building a 64-bit kernel with mips64 target toolchain and with CONFIG_BUILD_ELF64 and then trying to start remote gdb with that image I get a Segfault from gdb. What do you think is the cause of this? I guess its just file format mixup confusing gdb? any pointer from a gdb guru towards making this work? Ricardo
