wpa_supplicant takes several minutes to join WPA2 protected network

I want to bump the wpa_supplicant version I'm running, but I'm running
into issues where it sometimes takes several minutes to join a WPA2
protected network. The previous version (provided by Texas
Instruments, based on 2.1) didn't have this issue. The more recent
version provided by TI (based on 2.4) also contain the issue.
I have tried the latest master (355a5c8) and it shows the same behavior.
- Linux 3.13
- 4.1-rc1 backports (mac80211 etc)
- TI wl18xx WIFI
- AP SSID 'te-test5G', BSSID 14:cc:20:b4:e0:13 (seen with other APs
and channels as well)
What happens is that wpa_supplicant hangs at "wlan0-sta: State:
GROUP_HANDSHAKE -> COMPLETED" for several minutes, after which it
usually recover and authenticates successfully. This currently occurs
about 5-10% of the time, at least with this combination of system and
access point (but I've seen it with other systems and other APs).
Is there any way to debug this further?
