Netgear WNDR3800 - Atheros AR7161 rev 2

OpenWrt 19.07.0-rc2 r10775-db8345d8e4 / LuCI openwrt-19.07 branch git-19.344.41526-af5d665

I have this router configured on its 5G wifi as a WDS Client bridged to the 2.4G wifi acting as a repeater.

I have seen other reports of these errors but the ticket was closed with no action.

The reports appear randomly.

Same device here:

# head -n2 /proc/cpuinfo 
system type		: Atheros AR7161 rev 2
machine			: Netgear WNDR3800

With the same problem with the same AR_CR, AR_DIAG_SW and DMADBG values:
