[driverloader] ifconfig eth1 down -> Unable to handle kernel NULL pointer

[Lorenzo Martignoni]

Hello,

last night I installed the DriverLoader on my Asus-S1N notebook (a
centrino based). The wireless card works as a charm, but when I did a
"ifconfig eth1 down" I got this ugly message:

A similar messages appeared twice when I tried to shut down the system,
probably when the shutdown procedure was about to bring down the network
interfaces.

Is all that a normal behaviour?

Thank you.
