I have grsec set to high in kernel could this have anything to do with this problem ??

what should i do ? i m using iptables 1.2.8 with the patch you provide. Thank you for any info.

I don't think this has something to do with grsec. Most likely it is caused by CONFIG_MODVERSIONS. Turn that off if you don't really need it. Or try compiling both the kernel and the modules in one run.
Do not change the config after both have been built+installed without doing make clean and make dep. Recompiling+installing the modules without doing make clean and make dep again gave me similar problems once.
