Bob, Thanks for the pointer. I reviewed the ath9k looking for ordering problems in configuring the opmode. I could not see anything wrong. The opmode is set to NL80211_IFTYPE_MONITOR (6) when the device is started, and to NL80211_IFTYPE_MESH_POINT (7) on add_interface. At that point beaconing is enabled and there is a new reset. But I'm new to this card, so I'm probably overlooking something. I added the following tags to the code: DPRINTF(sc, ATH_DBG_FATAL, @@ -2207,6 +2208,7 @@ static int ath9k_add_interface(struct ieee80211_hw *hw, } /* Set the device opmode */ + printk("ath9k_add_interface: sc_ah=%p opmode=%d\n", sc->sc_ah, ic_opmode); sc->sc_ah->opmode = ic_opmode; /* And this is the dmesg output after executing modprobe ath9k debug=0x100 iw phy phy0 interface add mesh type mp mesh_id kangaroo iw dev mesh set channel 11 ifconfig mesh up dmesg: [ 1977.840919] ath9k_start: sc_ah=c7398000 opmode = 6 [ 1977.844540] ath9k_hw_set_operating_mode: 6 [ 1977.844972] ------------[ cut here ]------------ [ 1977.845710] WARNING: at drivers/net/wireless/ath/ath9k/hw.c:1583 ath9k_hw_set_operating_mode+0x36/0xb6 [ath9k]() [ 1977.846530] Hardware name: Uknown [ 1977.846890] Modules linked in: ath9k mac80211 ath cfg80211 rfkill [last unloaded: rfkill] [ 1977.848896] Pid: 1725, comm: ifconfig Not tainted 2.6.31-rc6-wl #18 [ 1977.849505] Call Trace: [ 1977.849931] [<c021f5ea>] warn_slowpath_common+0x60/0x77 [ 1977.850611] [<c021f60e>] warn_slowpath_null+0xd/0x10 [ 1977.851320] [<c988e12f>] ath9k_hw_set_operating_mode+0x36/0xb6 [ath9k] [ 1977.852243] [<c9890b2b>] ath9k_hw_reset+0x705/0xe8a [ath9k] [ 1977.852967] [<c0220034>] ?
