Somebody in the thread at some point said:
It seems to be a combination of problems with the iwl3945 driver,
SELinux
and NetworkManager.
Not sure one should blame iwl3945 for this. I updated a friend's
machine to development yesterday, on rt73usb. Development
wpa_supplicant crapped out during initscripts with a dbus error (dbus
doesn't seem to get started until ordinal 26 in the initscripts?).
NetworkManager was completely unable to authenticate to a WPA AP. I
downgraded NetworkManage and wpa_supplicant to the F7 versions and it
worked as usual.
