"simply stops" says little.  Are beacon frames transmitted?  Can you see 
inbound traffic?  Is the ap configured in a bridge and can you see 
outbound traffic from the wired interface?  What does ifconfig show for 
the device?

What is "no output"?  packets, console msgs?  what is "debug mode"? 
Have you looked at the output of wlanstats to see if it gives you a 
clue?  Can you see any frames with tcpdump or by sniffing from another

So you have crypto configured; have you tried w/o?

Sorry but your report does not help resolve your problem.  You have 
identified your card (mac+phy) but I'm not certain what code you are 
running (hal rev is useful).  Then provide the steps used to configure 
the ap.  Then explain what clients are used or otherwise describe how to 
reproduce your problem.  Once I have that I can try to reproduce the 
problem here.
