The driver is telling wpa_supplicant that you have been disconnected or otherwise lost association/authentication. Does wpa_supplicant work by itself? Do you still get disconnection events when using wpa_supplicant and issuing 'iwlist eth1 scan' periodically? Drivers should _not_ be disconnecting you when a scan is run; that's a driver bug, but that may be what you're running into.
