Subjectkernel oops with kernel-smp-2.4.20-20.9 (Unable to handle kernel NULL pointer dereference at virtual address 00000000)
Date
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
