That is the reason I need to add symbols externally.
Please dont ask me to rebuild the kernel, this is vanilla OpenSUSE 11.3 symbols and debug kernel should be available somewhere. I just need to know how/where to add the symbols. The problem is not reproducible, I need to debug the core which I have on hand.
Thanks.

Not sure about the symbol table, but was your kernel compiled
with -g flag (-g to the CFLAGS variable in the kernel Makefile) ?
