I've instead obtained a faster terminal, taken out the printk on ieee80211_master_start_xmit
as that wasn't telling us much and added a couple more printk's
One is in ieee80211_if_set_type at the only point where I can see u.ap.ps_bc_buf could get
initialised and as I suspected that doesn't get called.
case IEEE80211_IF_TYPE_AP:
sdata->u.ap.dtim_period = 2;
sdata->u.ap.force_unicast_rateidx = -1;
sdata->u.ap.max_ratectrl_rateidx = -1;
skb_queue_head_init(&sdata->u.ap.ps_bc_buf);
printk( KERN_DEBUG "Initiatilsing ps_bc_buf at %p\n",&sdata->u.ap.ps_bc_buf);
sdata->bss = &sdata->u.ap;
break;
The other is in ieee80211_tx_h_multicast_ps_buf just before tx->sdata->bss->ps_bc_buf gets
used. I haven't quite followed what ap structure bss should be pointing to at that time but I'm
presuming whatever it is doesn't contain an initialised ps_bc_buf hence the lock failure.
printk( KERN_INFO "About to queue skb %p to buffer %p\n",tx->skb, &tx->sdata->bss->ps_bc_buf);
skb_queue_tail(&tx->sdata->bss->ps_bc_buf, tx->skb);
