Hello, I use debian lenny and when I do these steps kernel always segfault. 1. configure your /etc/network/interfaces add inet6 adres with /52 netmask and restart networking 2. change your /etc/network/interfaces change mask to 64 3. restart networking and check IPv6 address - It has always /52 4. so ip del addr .... dev eth0 5. ip add addr .../64 dev eth0 Now kernel segfault. It doesn't happend when you use only ip or ifconfig commands, only with debian networking scripts.
