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.
