Please send the full panic output.

netfilter problem

[saravanan chanemouganandam]

Hi,

I have a problem in compiling "netfilter" for Iptables support into the 
linux 2.6.12 kernel version. I have manually enabled the config option 
"CONFIG_NETFILTER=y" and all netfilter configuration CONFIG_IP_NF_* manually 
in to the "mainstone_defconfig" file for my target arm board.

Now, the problem is that, on "make vmlinux", the files under the 
"linux/2.6.12/net/ipv4/netfilter" directory doesn't gets compiled leaving 
built-in.o and this annoys me a lot.

Could any one please precise me, what are the options I need to check or 
enable in the config, Kconfig or in Makefile to get the "netfilter" compiled 
into my kernel?

Thanks.

Regards,
Sara

If you run 'make menuconfig' on the other machine, you will see that some
CONFIG_IP_NF_* are moved to CONFIG_NETFILTER_XT_* and NETFILTER_XTABLES is
added.
