I wonder why that is happening on those NICs. This is in normal hostap+sta WDS setup, right? Rather than adhoc or mesh? (That changes how the MAC handles beacon TX.) > Jan =A01 00:01:32 wlanmon: (RTM_IEEE80211_JOIN) [wlan1] [00:c0:c1:cb:6c:c= 2] > Expensive timeout(9) function: 0xc05aa150(0xc58c3b80) 0.013488188 s What was this caused by again? Which part of ath_calibrate() was causing the issue? Is it the noise floor save/load? IQ calibration? ANI? Anything else? > Jan =A01 00:16:45 wlanmon: (RTM_IEEE80211_ASSOC) [wlan2] [00:c0:c1:cb:6c:= c3] > lock order reversal: > =A01st 0xc59126c0 ath1_node_lock (ath1_node_lock) @ /usr/src/sys/net80211= /ieee80211_ioctl.c:1326 > =A02nd 0xc5911014 ath1_com_lock (ath1_com_lock) @ /usr/src/sys/net80211/i= eee80211_node.c:2510 Blah. So the above is in setmlme_dropsta() -> domime() -> ieee80211_node_leave() (MLME_DISASSOC or MLME_DEAUTH in hostap mode, on a broadcast address). What's the second path? How the heck does ieee80211_parse_beacon() call ieee80211_node_leave() ? Adrian
