I just had an issue with file permissions.  If you see the following in your 
logcat:
D/wpa_supplicant( 1850): Configuration file 
'/data/misc/wifi/wpa_supplicant.conf' -> '/data/misc/wifi/wpa_supplicant.conf'
D/wpa_supplicant( 1850): Reading configuration file 
'/data/misc/wifi/wpa_supplicant.conf'
E/wpa_supplicant( 1850): Failed to read or parse configuration 
'/data/misc/wifi/wpa_supplicant.conf'.
D/wpa_supplicant( 1850): Failed to add interface wlan0
D/wpa_supplicant( 1850): : Cancelling scan request
D/wpa_supplicant( 1850): : Cancelling authentication timeout

A temporary workaround is to chmod 666 data/misc/wifi/wpa_supplicant.conf

Ideally this would not be world writable but maybe this is related to process 
priv work in progress.
