    That seems like a hackish thing to do. Could you mistake other pages
    with the same count as pages you have reserved?

    This suggests a problem with RHEL3. If it works fine on a vanilla 2.4
    kernel, then by all means try to get support from your vendor. If it
    works fine on the latest 2.4.X and 2.6.X linux-kernel is probably not
    the best place to look for help, although I can't blame you for trying.
    Maybe someone here already knows the answer, but unfortunately, it is
    not me.

    Sorry if I missed context from your earlier posts.
