In 2.1.103, there is a problem in net/ipv4/ip_fw.c:ip_init_chain().
It allocates memory for ip_chain, and the amounts of memory depends
the number of processors (smp_num_cpus). However, we don't know the
number of processors yet, because sock_init() runs before smp_init().
Because of this, kernel gets OOPs when using network.
Here is a patch to point out the problem. As I don't know much about
the order of initilization, it may be wrong.
Thanks,
