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.

Thanks Malyudi. Thats sounds like a reasonable approach. I did try to search kernel-debug RPMs for my kernel could not find any. May be I should just keep looking.

On that note, I wonder what is the difference between kernel-base, kernel-default, kernel-devel, and similar other RPMs. I guess some contain binaries, some contain unstripped binaries and some contain soruces/headers. But which is which ?? I hate distros for creating so many RPMs. They could have included ALL of this in one RPM and users would not have minded.
