A new Flyspray task has been opened.  Details are below. 

User who did this - FredFirestone (FredFirestone) 

Attached to Project - OpenWrt/LEDE Project
Summary - Repeated connection losses, maybe due to "Rate marked as an HT rate ..." dump - see old #6411
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Low
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Problem occurs on a TL-WR1043ND v1 / Atheros AR9132 rev 2 and seems to cause connection loss. As it repeats connection is lost frequently (like every 5 minutes).

Firmware is OpenWrt 19.07.7 r11306-c4a6851c72 / LuCI openwrt-19.07 branch git-21.044.30835-34e0d65

Device is configured with multiple vlan's and SSID's.

https://dev.archive.openwrt.org/ticket/6411.html#comment:81 indicates a buggy hardware / firmware corrupting datastructures but I didnÄt see anything regarding "TX DMA" in my logs either before or after.
