This is a shot in the dark, but I have a possibly similar issue with my
Intel  6205 (iwn) card. It appears that thee is a race involving the timing
of the iwn (wlan0) coming up and the start of the wpa_supplicant.

I see the interface start, and aesociate but immediately go down. dhclient
starts, but fails. If I kill the interface (service netif stop wlan0) and
manually start it (ifconfig wlan0 up), it comes up fine. I can then start
the wpa_supplicant and dhclient to get it working. From this point, it
remains stable.

If I just let it bounce up and down, it usually will eventually come up,
but it can take some time and, on occasion it simply fails to some up
unless I intervene.
