Hi,

Some of my Redhat 6.0 systems always have reboot hang problem on 
iptables script with niu driver interface up. After adding some debug 
stuff, I can see the system alway hang on " modprobe -r xt_state". What 
could be the cause of it? Does niu driver need to handle some 
calls/ioctls that currently not implemented in the niu driver?

Thanks,
Joyce
