    Greetings all.

    Im getting the error message "Unable to handle kernel NULL pointer
    dereference at virtual address 00000000" when trying to load (ifup eth1)
    eth1 with kernel-smp-2.4.20-20.9. It works fine with non-smp package from
    RH.

    Now im not sure if im using the ksymoops tool correctly, as im getting error
    using it ...
    but heres the output anyway :

    [root@localhost oops]# ksymoops -v /boot/vmlinux-2.4.20-20.9smp -k
