The kdb code at least seems to support the NEW_UNWIND code by using unw_init_frame_info(). You code mentions that it should be using activation records and I was wondering what that's all about. I've been reading David Mosberger chapter on Stack Unwinding and I'll check the kernel code for perspectives on the code. I suspect that the gdb unwind code and the HP-IPF-unwind library (available on request) are likely an overkill and only needed for C++. Perhaps you could take a few minutes and provide a few pointers on how to save time in adding unwind support. -piet
