2.6.26-1-686 break wlan connectivity on Thinkpad T61p

[Rainer Dorsch <rdorsch@web.de>]

Hello,

I just noticed that the current lenny kernel 2.6.26-1-686 breaks WLAN on my 
T61p. It has an 

03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN 
Network Connection (rev 61)

wlan adapter and with 2.6.26-1-686 I get

paddy:~# ifup wlan0
Error for wireless request "Set Encode" (8B2A) :
    SET failed on device wlan0 ; Invalid argument.
Failed to bring up wlan0.
paddy:~# 

whereas when I boot the T61p with 2.6.25-2-686, the wlan works flawless.

I am happy to provide further debug information.

My configuration:

from /etc/network/interfaces

iface wlan0 inet dhcp
        pre-up ip link set wlan0 up
        pre-up iwconfig wlan0 essid ABC
        pre-up iwconfig wlan0 enc 12345678901234567890 open
        wpa-conf /etc/wpa_supplicant/leap.conf
        wpa-driver wext

and

paddy:~# cat /etc/wpa_supplicant/leap.conf
#eapol_version=1
# next two, YMMV
#ap_scan=0
#fast_reauth=0
#ctrl_interface=/var/run/wpa_supplicant

network={
        scan_ssid=1
        ssid="IBM"
        key_mgmt=WPA-EAP
        eap=LEAP
        identity="dorsch@test.org"
        password="aslkjfa%@sd"
}

Any hints are welcome.

Thanks,
Rainer
