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.

try to check opensuse repo, see which one provide kinda "debuginfo"
package for your kernel (at least that's how Fedora/RHEL call it).
Usually it will be located under /boot with quite obvious name
(suffixed with "debug" or similar) or you could just try to use
vmlinux as the symbol file

NB: make sure you use the very same debuginfo package with your
current kernel version. Any slight difference could yield very
different symbol addresses.
