hello, i'm running a xen enabled guest kernel and having APF as a firewall 
handler for me and i have about 1200 iptables rules, most are drops, i have my 
guest kernel fails about 2 times a day with this message, i contacted the xen 
devs. but i think they believe it's an iptables related issue, i'm running FC4 
and have upgrade from iptables v1.3 to v1.3.5 latest and the kernel is 
2.6.16.13, thanks and here's the kernel error...
