IPW2100 not able to associate using WPA

Hi,
 
I have no luck with using ipw2100 and WPA.

Hardware: Thinkpad R51 with Intel 2100 WLAN
AP: Siemens Gigaset SE515

OS: Ubuntu 6.06, 6.10 and Suse 10.1

WEP works fine, 99% signal level.

When trying to connect with WPA I get the following log messages:

[17180549.772000] ipw2100: Fatal interrupt. Scheduling firmware restart.
[17180560.632000] ipw2100: Fatal interrupt. Scheduling firmware restart.
[17180562.984000] ipw2100: Fatal interrupt. Scheduling firmware restart.

wpa_supplicant is called like that:

wpa_supplicant -dd -Dwext -ieth1 -c/etc/wpa_supplicant.conf

and /etc/wpa_supplicant.conf looks like that:

ctrl_interface=/var/run/wpa_supplicant
network={
        ssid="proton"
        scan_ssid=1
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        #psk="thisisthepassword"
        psk=b5108a57f40849d329b564f837d5898ec7ccb6a4ede7e1b5ddece8d1c5f23571
        priority=5
}

iwlist s says this:

and the interesting part of wpa_supplicant's output is this:

The exact same wpa_supplicant setup works fine with ndiswrapper and the
lastest IBM drivers for the R51.
