Subject: compat-drivers 3.7-rc1: cfg80211 fails to load on 3.0.0-26-generic-pae [AV#3438]

Dear developers,

I'm trying to use compat-drivers to gain support for the Intel Centrino
Wireless-N (iwlwifi driver) on the Ubuntu Oneiric kernel backported to
Lucid (3.0.0-26-generic-pae). The driver compiles but fails to install,
with the following error:

[ 578.661869] Compat-drivers backport release: compat-drivers-v3.7-rc1-6
[ 578.661879] Backport based on linux-stable.git v3.7-rc1
[ 578.661885] compat.git: linux-stable.git
[ 578.664089] cfg80211: Unknown symbol simple_open (err 0)

Does anyone know what this means? Did Ubuntu change the kernel enough that
compat-drivers compatibility layer is confused?

Cheers, Chris.

Are you sure that you installed the modules correctly on your system?
simple_open() is a new symbol that should normally be provided by the
compat layer (compat.ko). Do you have any undefined symbol warnings at
the end of the building process?
