Timeout after move to GROUP_HANDSHAKE state

[Aric D. Blumer]

Can anyone tell me what wpa_supplicant is waiting for when a WPA 
association times out after a move to the GROUP_HANDSHAKE state?  The 
output of wpa_supplicant 0.6.9 is shown below.  I am trying to get a 
wifi driver working, and I suspect it's not doing something it should 
be.  Knowing what would help me solve it.  Thanks.
