OK, I've done the formatting:
I'm using a 3COM PCI card: 3CRDAG675 based on atheros 5212 chipset. Driver
is madwifi driver ng-r1702-20060810.

I have configured wpa_supplicant to be able to connect to a dot1x peap-
mschap network.
After connecting to the network, I trigger the client to roam. For this,
I'm using following two wpa_cli commands:
{{{
wpa_cli bssid 0 00:11:22:aa:bb:cc
wpa_cli reassociate
}}}
After the wireless client roamed afew times between two APs of the same
network, the computer freezes.
It doesn't respond to any key combination.
This is how the last printed screen of the machine looks like:

I can get the wireless client in this state every time, by asking it to
roam.
The crash appears after a variable number of roamings.
