I believe this problem appeared on or about r36682, which coincides with a
hostapd update to AA. This suggests a regression in hostapd w/r/t/ to
beacon interval code.
I can confirm the same problem happens when attempting to specify
beacon_int on a single psk2-encrypted adhoc interface, not just with
multi-VAPs as with the original poster. My test was on an Engenius
EOC-1650, atheros platform, running Attitude Adjustment r38347 that I
compiled.
The error quoted below goes away when I comment out the "beacon_int" line
in /etc/config/wireless. Likewise, this wireless config, with the
beacon_int line, works just fine under Attitude Adjustment r36669, before
the hostapd update.
