compat-wireless-2008-12-11 disassociating on intel pro wireless 4965

[techmin <info@techemia.com>]

Hi All

I have problem with last compact wireless
i suppose the problem is present on 2.6.27 series linux kernel
this is the link of the bug for ubuntu
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/302069

(the ubuntu 8.04 with 2.6.24 kernel don't have problem, the wireless 
work correctly)

The problem is present on ubuntu precompiled kernel and on compiled 
compat-wireless-2008-12-11 from source.

I suppose the core of the problem is:
wlan0: disassociating by local choice (reason=3)

This is the dmesg
