complete dmesg

I just upgraded from 4.4 to 4.12, I start to see these king of warnings.
I am using TP-LINK TL-WN781ND V2.2 (Qualcomm Atheros AR9485), configured as AP with hostapd WPA2-PSK-CCMP.

If more info is needed please let me know.

Comment 3 Johannes Berg 2018-01-23 07:55:11 UTC
This is a driver bug, fixed by https://patchwork.kernel.org/patch/10168963/
Comment 4 Gerardo Exequiel Pozzi 2018-01-25 17:43:54 UTC
Thanks you! Tested and fixed! Will be submitted for stable/longterm and mainline branch?
Comment 5 Gerardo Exequiel Pozzi 2018-02-06 18:38:02 UTC
@Johannes: I tested against the USB version (ath9k_htc), and the same thing happens in function ath9k_rx_prepare(). I need to open a separate bug request?
Comment 6 Johannes Berg 2018-02-06 18:41:05 UTC
probably better, yeah, otherwise somebody's going to get confused
