Package: kernel-image-2.6.9-1-686
Version: 2.6.9-3

Kernel module ipip does not has the `used' mark, even if it's necessary.
As result, user(root) can rmmod it, while ipip tunnels still exists, so
ifconfig crashes. 
On the other hand, 2.4.x kernels marks ipip module as used:
Here is the transcript:

2.4.27:

~# lsmod | grep ipip
~# iptunnel ls
~# iptunnel add mode ipip local 10.0.0.14 remote 10.0.0.1
~# lsmod | grep ipip
ipip                    7072   1  (autoclean)
~# rmmod ipip
ipip: Device or resource busy

2.6.9:

~# lsmod | grep ipip
~# ifconfig
