Open /etc/rc.config and try to find something like REINIT_MANDB and
DELETE_OLD_CATMAN and RUN_UPDATEDB. Set all of them to "no".

Are you sure that you used the right System.map? Was this the first
Oops? Only the first Oops of a kernel is meaningful. All Oopses after
that are mostly useless for tracking down the bug.
