Any idea why it would be sent? Did you kill wpa_supplicant or something similar? In any case, we wouldn't expect to get a deauth with reason 15 (WLAN_REASON_4WAY_HANDSHAKE_TIMEOUT) then. Hmm. Maybe that's why wpa_supplicant was trying to disassociate as well? Still, we should of course not crash :) > May 16 10:10:58 larrylap kernel: eth1: deauthenticate(reason=3) > May 16 10:10:58 larrylap kernel: eth1: RX deauthentication from 00:1a:70:46:ba:b1
