We know this issue happen on kernel v4.15 and v4.18, but kernels before v4.15 were not tested. The issue happens with Google Mesh, which has 802.11ac capability. I haven’t been able to reproduce the issue with an 802.11n router (yet).

Do I need a special WiFi router which support RX reorder to reproduce the issue? It's introduced by commit c545070e404b (“ath10k: implement rx reorder support”).

As far as I understand, the issue "failed to pop paddr list: -2” happens because ath10k_htt_rx_pop_paddr() fails to find skb in skb_table, hence trigger the warning. Those function are introduced by commit "ath10k: implement rx reorder support”. Since I’ve never seen such issue on my WiFi routers, while it happens to Stephan frequently, so I want to know if the “RX reorder support” is a feature that’s only supported by certain WiFi routers.
