Failed to scan Network with the 2200BG

Hi,
 
I try to use the IPW2200 on a powerpc platform.
Software & firmware versions :
1) v1.2.0 of ipw2200 
2) v1.2.15 of iee80211 stack
3) Linux 2.6.16.11
4) v3.0 firmware of 2200BG
 
I make insmod ipw2200.ko to start the driver.
 
Its seems to work at the beginning but when the board scan the network
nothing 
happen...
 
I dumped the channel_results struct on the Scan result notification and the 
field accumulated_rssi of ipw_cmd_stats indicates there is some network.
 
But when the driver called ipw_associate function, there is nothing in the
priv-
>ieee->network_list ???
 
How does the driver or else add network in this network_list ?
 
At the end, the board seems to be shutdown because the driver failed to send

anay command => Failed to send SCAN_ABORT.
 
I have a strange trace means that the system try to transmit a frame with no

association : ipw_net_hard_start_xmit Tx attempt while not associated.
 
I put the trace of the driver :
