I've seen nothing that would help me diagnose the problem.  Try building 
the 80211debug tool from src/tools/tool/ath then do

80211debug scan+assoc+auth

and bring the interface up (this is roughly equivalent to ifconfig ath0 
debug but 80211debug is much more useful for controlling the debug msgs 
in the 802.11 layer).  The console log msgs should provide enough 
information to tell you what's going on.
