Xiaomi AX3600 / ath11k: Failed to flush transmit queue and wifi disruption

Hi there, I acquired a used AX3600 and got most recent OpenWRT snapshot ( OpenWrt SNAPSHOT r22496-d98c8fc06d ) Right now I did a speed test with 2 devices (Intel Dual Band Wireless AC 8265 + 1x Google Pixel 3a, both Wifi 5 afaik) connected to it. In the middle of the speed test, one wifi connection (Google Pixel 3A) dropped and came back a few seconds later while the second wifi connection (Intel Wifi 8265) only stopped transmitting any data for a few seconds. Logfile: Tue Apr 4 16:35:07 2…

which cites this patch :

https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/kernel/mac80211/patches/subsys/331-wifi-mac80211-flush-queues-on-STA-removal.patch;h=00232ec1b9e9f6d077c5b17827bde675c9fec2b6;hb=d54c91bd9ab3c54ee06923eafbd67047816a37e4

In my network I have two APs on the same SSID so I have clients that move around the house re-associating a lot with whichever one is closest, and this is calling flush a lot. And this seems to be contingent in the wifi issues with ath11k ?

Edit: wait, is this the patch anom3 already tried removing at the top and whilst it had some success it wasn't successful ? in which case, the next thing to try is the NSS build ? Or this bss coloring config (was that for every client, or on the router/AP ?) ? Or ... drop the router/AP in a bin and buy another one with different chipset .....
