Latest kernel/wireless updates breaks WPA(-PSK?)

Description of problem:
With the following kernels I can connect without problems using either the Intel 3945 in the laptop or an Atheros-based PCMCIA card:
kernel-220.127.116.11-55.fc9.i686 (officially released)
kernel-18.104.22.168-72.fc9.i686 (last internal kernel on koji before wireless updates)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot into 22.214.171.124-76.fc9
See NetworkManager trying to connect (LED blinks) but never completes the connection until timeout.
NetworkManager can create WLAN WPA connection
I tried by hand with
# service NetworkManager stop
# wpa_supplicant -i wlan0 -c wpa_supplicant.conf -dd
I'll attach the OK/error log files.
Created attachment 310863 [details]
wpa_supplicant debugging logfile from kernel-126.96.36.199-72.fc9.i686 (OK)
Created attachment 310865 [details]
wpa_supplicant debugging logfile from kernel-188.8.131.52-76.i686 (BROKEN)
When you compare the OK to the BROKEN log file you see that everything works up
State: 4WAY_HANDSHAKE -> GROUP_HANDSHAKE
In the error case it never seems to receive the group ACK from the base
I also tried the latest kernel on Koji
which has even more wireless updates from upstream: still broken :-(
Yeah, me too =(
Booting 184.108.40.206-76 I can't connect to my wireless network. Booting back with
220.127.116.11-55 works fine as expected.
I am using an iwl3945 NIC.
Connecting to not protected networks works fine with both kernels, the problem
seems to be with the ones that are protected.
I think this may be the same bug as #453882 which I posted earlier.
Note that WEP still works, so if you live in an area where you doubt your in
range of anyone who knows how to crack WEP, you could use that, and then disable
remote management of your router along with MAC address filters as a workaround
until a new version of wpa supplicant is here.
Latest kernel from koji
is still broken.
I also installed the only kernel between -72 (OK) and -76 (broken) from koji
It is also broken. That limits the culprit down to
Looking at the changes I would put my money on one of those from -73:
Harvey Harrison (11):
mac80211: add helpers for frame control testing
mac80211: remove ieee80211_get_morefrag
mac80211: make ieee80211_get_hdrlen_from_skb return unsigned
mac80211: add utility function to get header length
mac80211: wpa.c use new access helpers
mac80211: use new helpers in util.c - ieee80211_get_bssid()
mac80211: wme.c use new helpers
mac80211: rx.c use new helpers
mac80211: tkip.c consolidate tkip IV writing in helper
mac80211: tkip.c fold ieee80211_gen_rc4key into its one caller
mac80211: tkip.c use a local struct tkip_ctx in ieee80211_get_tkip_key
