Is your box acting as router, or host?
% sysctl -a |grep ipv6|grep forwarding

What is happend if you let the interface down and delete it before
becore rebooting?

Thanks.

lt:~# sysctl -a |grep ipv6|grep forwarding
net.ipv6.conf.atman6.forwarding = 0
net.ipv6.conf.eth1.forwarding = 0
net.ipv6.conf.eth0.forwarding = 0
net.ipv6.conf.lo.forwarding = 0
net.ipv6.conf.default.forwarding = 0
net.ipv6.conf.all.forwarding = 0

atman6 is sit device, ipv6 is loaded as module.

OK, if interface is down, system is rebooting correctly.

I had made tests with shutdown interfaces, but i shutdowned wrong sit 
interface. :( Sorry for that. 

Anyway, ipip interfaces no need to be shutdown before reboot. Is it
problem in sit_cleanup()?
