You can't do that, because, unlike some other platforms, MIPS ABIs do not use a fixed frame layout. You need at least symbol information or, preferably, debug records to be able to construct a backtrace. These can be attached to the ELF executables used and are not easily reachable from the kernel. What's the point anyway? Just use GDB or other widely available user tools. Maciej
