I have managed to trace the problem to a clash between hostap and
wlan-ng:
if (register_wlandev(wlandev) != 0) {
WLAN_LOG_NOTICE0("prism2sta_cs: register_wlandev() failed.\n");
goto failed;
}
And in the real problem...
./p80211/p80211netdev.c:
if (register_netdevice(dev)) {
if ( i >= 0 ) {
wlandev_clear_index(wlandev);
}
rtnl_unlock();
return -EIO;
}
I don't understand this fully - but I had hostap_pci loaded and providing a wlan0 device (from the built in wifi on this laptop) but I was wanting to test a usb device, with wlan-ng which seems to be barfing because it wants to use wlan0.
Is this a hostap bug or a wlan-ng bug? or both :O)
