 yes i DO use IPv6 intensively.
 
 this machine has native IPv6 connectivity, offers native connectivity and 
 over TUN (ppp) and tunnels over gif.
 
 options added kernel compiled machine rebooted. on what messages should i 
 look for?
 
 
 now i know that sometimes 2 machines in my IPv6 network crashes at the 
 same time? special kind of packets?
 
 will my firewall config and kernel config help?
