Subject: 2.6.35, netfilter/iptables not working with 32bit userspace +
	64bit kernel?

Hello!

I have server/firewall running Debian lenny with 32bit userspace and  
64bit kernel. After upgrading from 2.6.34 to 2.6.35, I couldn't get  
any new chains work. Simply doing (with 32bit iptables)

   iptables -N new_chain
   iptables -A OUTPUT -j new_chain
   iptables -A OUTPUT -j ACCEPT

cause output to freeze. "iptables -L -vn" shows:

Chain OUTPUT (policy ACCEPT 3397 packets, 637K bytes)
  pkts bytes target     prot opt in     out     source         destination
     3   252 new_chain  all  --  *      *       0.0.0.0/0      0.0.0.0/0
     0     0 ACCEPT     all  --  *      *       0.0.0.0/0      0.0.0.0/0

Ping shows "ping: sendmsg: Operation not permitted".

With recompiled 64bit iptables, example above works fine.
