I noticed a similar bug, but it happens only if wlanconfig is called at 
least twice. For instance, you create a first instance of ath0, destroy 
it and then create a new instance of ath0. Is that your case?

If this is the case, it seems the second instance of ath0 receives 
packets that still points to the keycache of the first instance and 
then, you hit a kernel panic. I might have wrote down more details 
somewhere, but like to get your confirmation before digging up my notes :-)
