Isn't this the Oops Joonwoo Park wanted to patch with
"[PATCH] iwlwifi: fix oops on wep key insertion" 27/5/2008
invalid length of webkey that would/should be handled in mac80211?

Yes, it looks like.
Ummm, what has a wep key to do with me trying to access a
WPA2-Personal
encrypted net ?
Not sure yet, but mac is trying to assign default/static wep key.
:iwlcore:iwl_send_static_wepkey_cmd+0xcb/0xd5
:iwlcore:iwl_set_default_wep_key+0xa2/0xbc
Try to set the encryption explicitly
network={
psk="*************************"
scan_ssid=1
ssid="dlink"
pairwise=CCMP
group=CCMP
}
That didn't help at all.
What's more it prevented the wifi to work on 2.6.24.7 so I had to remove
the
lines again...
So what's your AP configuration TKIP?
I've switched to clean WPA2-AES on the AP, but it does not do any
difference... I still get the oops...
I would like to see the log of this one
Second try also with sw decryption:
in /etc/modprobe.conf
options iwl4965 swcrypto=1
That works.
I now run a clean 2.6.26-rc5
Okay thanks for checking this one.
I also tried to bisect between 2.6.25 and 2.6.26-rc1 and ended up with:
[root@5720g linux-2.6]# git bisect good

cfg80211 API for channels/bitrates, mac80211 and driver conversion
Any more I can provide to help finding the bug ?
Just the log from AES try with I will try to reproduce this as soon
as I get to this particular AP and 64 bits kernel.
with wpa_supplicant.conf:
network={
psk="*************************"
scan_ssid=1
ssid="dlink"
pairwise=CCMP
group=CCMP
}
I also rebuilt the 2.6.26-rc5 with enabled mac* and iwl* debug options,
so the configs are:
