Even with the most recent brcmfmac code ppl keep seeing WARNINGs from brcmf_netdev_wait_pend8021x [0]. Hante suggested using CONSOLE for debugging some firmware crash so I decided to see I it could also help understanding WARNINGs. I believe it did. First of all, I can't reproduce these problems reliably. One evening I got WARNINGs one by one and I could work on my debugging patch easily. Yesterday when I got my patch complete, it took me 10+ hours to get a single WARNING. Anyway, it seems to me that sometimes AMPDU stalls in the firmware. It seems firmware has some AMPDU watchdog that notices the problem and kicks in. It prints some debugging info and starts cleaning up process. If brcmf_netdev_wait_pend8021x gets called shortly after that (I set wpa_group_rekey=30 in hostapd to get brcmf_cfg80211_add_key called more often) it results in a WARNING.
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.
