Hi Larry,

I tried reproducing this, but not luck so far. Could you provide me with 
syslog including both kernel messages and wpa_supplicant. From the log 
you provided it seems mac80211 triggers the disassoc. It could be a 
beacon timeout, but I would like to be sure. More debug output from 
mac80211 itself would also be helpful to understand the issue.
