I have looked at this now a bit and I don't think this is an iwl3945
problem. Scanning seems to stall in some situations and iwl3945 doesn't
even receive the scan command.
Here's an example what's happening with wpa_supplicant from debian
unstable:
$ sudo ifup wlan0
[ 104.468073] iwl3945 0000:03:00.0: firmware: requesting iwlwifi-3945-2.ucode
[ 104.533234] iwl3945 0000:03:00.0: loaded firmware version 15.32.2.9
[ 104.612049] phy0: device now idle
[ 104.613091] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 106.968392] phy0: device no longer idle - scanning
[ 109.561397] phy0: device now idle
[ 109.563737] wlan0: deauthenticating by local choice (reason=3)
[ 109.563743] phy0: device no longer idle - in use
[waited a while]
$ sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Device or resource busy
$ sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Device or resource busy
$ sudo wpa_action wlan0 stop
[ 191.649653] wlan0: deauthenticating by local choice (reason=3)
[ 191.697619] phy0: device now idle
Also I have been able to reproduce the problem once with iw. For some
strange reason I have had to reboot my laptop to reproduce this,
unloading all wireless related modules (expect rfkill which I can't
unload due to dependencies) is not enough.
