Above log was from D-Link DIR-885L. I can also see WARNINGs on SmartRG SR-400ac with 2 x 43602a1. Unfortunately brcmfmac43602-pcie.ap.bin doesn't seem to have so many debugging messages so despite having CONSOLE enabled, I didn't get anything interesting :( Below you can find 4 logs that look pretty identical to me. At the end of e-mail there is a confirmation of CONSOLE working.

I think I found a way to reproduce this more reliably! It seems doing a static transfer from few devices (I use iperf) doesn't matter much. So this is what I do to get WARNINGs on my DIR-885L: 1) Notebook sending data with iperf to DIR-885L 2) iPad playing YouTube using SR400ac on the same channel 3) I take my 2 smartphones to the next room and keep switching between 2 out of 3 SSIDs of DIR-885L. Once connected I run iperf for a bit randomly. It seems I can get a WARNINGs every few minutes this way. > Enough talking, please take a look at my debugging log. Does it give you > enough hint? Could you review/debug firmware's code responsible for > AMPDU? FWIW Merlin users (so no brcmfmac invovled) also saw this [1]. I grabbed more logs I can share now. I believe they show the same: stall and warning soon after ampdu_dbg/wlc_ampdu_watchdog. I'm attaching them anyway. Please note that calls to __send_key_to_dongle happen all the time, I'm including them in logs for a context. You can treat them as an indicator that things are going well. It's ampdu_dbg + wlc_ampdu_watchdog that lead up to the WARNINGs.

messages in official firmware release. It would be great to have a timestamp for these skb when they arrive in brcmfmac or transferred to firmware (or both). The obvious solution would be to increase the pend8021x timeout in brcmfmac. Probably another solution would be to exclude EAPOL frames from A-MPDU in firmware. That still does not solve the A-MPDU stall.
