tun failing: SIOCSIFADDR: No such device

[Geoff Reidy <greendog@pacific.net.au>]

Hi all,

I am running sid and since upgrading kernel-image-2.6.11-1-k7 from 
version 2.6.11-3 to 2.6.11-5 I can't get a tun interface to work.
The tun module is loaded and the device is there:

crw-rw----  1 root root 10, 200 2005-05-31 20:25 /dev/net/tun

but the interface won't come up:

# ifconfig tun0 127.20.0.1
SIOCSIFADDR: No such device
tun0: ERROR while getting interface flags: No such device

Is it a bug or have I broken something?

Regards,
Geoff
