Bug Description

wpa_supplicant eats lot of CPU resources and generate repeated errors:
iwl3945 0000:03:00.0: Radio disabled by HW RF Kill switch

This error appears even if WiFi switch is set to off.
'sudo modprobe -r iwl3945' disables wpa_supplicant and errors stop.

If I switch WiFi on and connect to my hotspot everything back to normal.
