Ok, on the ath card the issue seems to be related to the interaction
with the AP and the roaming mode... This problem is exacerbated by the
fact that I sometimes manage to get the card into a state where I can
see outbound 802.11 frames with tcpdump, but never see inbound packets,
i.e. probe responses... Those are the instances when it scans
forever... Ejecting the card and re-inserting gets me back to a useful
state.

This is long, sorry...

This is what happens when I plug the card in and wpa_supplicant tries to
configure the card.

It continues scanning, but never associates again...

When I "wpa_cli term" wpa_supplicant, it leaves the card like this...

It's all good now...

I either have or can provide tcpdumps of each specific case if that
helps more, but I figure this message is long enough already.

Now, off to debug the other issues with the wi card, sigh...
