So if I read it right, after an interface down/up or an idle IPS cycle they can go out fo= r a station that is gone, and maybe even before rtw_sec_enable_sec_engine() has run. Resume from WoWLAN looks similar, rtw_wow_stop() starts the HCI while the WoWLAN firmware is still loaded and rtw_wow_swap_fw() follows right after. PCI drops what is left in its rings in rtw_pci_stop(), through rtw_pci_dma_release(). Maybe doing the same here would be safer, purging rtwsdio->tx_queue[] with ieee80211_purge_tx_queue() and clearing tx_queue_stopped[] with a wake of those queues, instead of the rearm. What do you think? The stop/start cycling in the cover letter was also run on 7.2.10, where tx_handler_data->work is still a work_struct and the 8723BS HISR mask is not there yet, so I guess the board ran a backport. Was this version run on the board as posted? Best regards, Luka Gejak
