I have just confirmed that this problem also exists with the following
setup:

AP: linux-2.6.15.4 + hostap-driver-0.4.7 + hostapd-0.5.1 + WPA2-PSK
CCMP + radvd-0.9.1

STA: linux-2.6.15.4 + hostap-driver-0.4.7 + wpa_supplicant-0.5.1

Whenever radvd sends out an ICMP6 router advertisement the following
messages are printed in the STA syslog:

Feb 13 19:10:43 fangorn CCMP: decrypt failed: STA=00:02:6f:37:fc:68
Feb 13 19:10:43 fangorn wifi0: decryption failed (SA=00:02:6f:37:fc:68) res=-5

A tcpdump running on the AP shows the ICMP6 router advertisements just
fine.

So it would seem that this is related to either hostapd or
wpa_supplicant - not ipw2200/ieee80211 as first assumed
(see http://bughost.org/bugzilla/show_bug.cgi?id=810)?

Hope someone will be able to reproduce this problem.

Regards,
Brix
