Hi, Next time you do this, can you do this: wlandebug +crypto +assoc +state I'd like to see what's actually going on behind the scenes. so: May 9 21:08:59 gateway sudo: lev : TTY=pts/1 ; PWD=/usr/home/lev/bin ; USER=root ; COMMAND=/sbin/sysctl dev.ath.0.debug=0x900000020 .. then a bunch of time, which I guess is you doing UDP: May 9 21:16:25 gateway kernel: ath0: ath_tx_tid_drain_print: norm: node 0xffffff8000d7f000: bf=0xffffff800085d8e0: addbaw=0, dobaw=0, seqno=715, retry=0 May 9 21:16:25 gateway kernel: ath0: ath_tx_tid_drain_print: node 0xffffff8000d7f000: bf=0xffffff800085d8e0: txq[1] axq_depth=502, axq_aggr_depth=0 May 9 21:16:25 gateway kernel: ath0: ath_tx_tid_drain_print: node 0xffffff8000d7f000: bf=0xffffff800085d8e0: tid txq_depth=1 hwq_depth=503, bar_wait=0, isfiltered=0 May 9 21:16:25 gateway kernel: ath0: ath_tx_tid_drain_print: node 0xffffff8000d7f000: tid 0: sched=1, paused=0, incomp=0, baw_head=0, baw_tail=0 txa_start=51018, ni_txseqs=61249 .. so: * hardware queue depth is 502 frames * no aggregates * there's only one frame in the TID txq, but 503 frames from that TID in the hardware queue * it's scheduled for more frames but there's likely no space left in the TXQ. But there's no hardware reset until you do a forcebstuck. So I guess that first one is actually a disassociate/reassociate bug more than anything. I bet this is what is actually going on. Can you please do the wlandebug above, so we can see if it's actually disassociating and not transitioning back through SCAN/ASSOC states? Thanks, adrian
