running two RT-AC66U with Firmware-Version:3.0.0.4.270.26 (Merlin build).
one in AP mode, the other in media bridge mode.

in dmesg of AP:

I just have accidentally noticed exactly the same messages on my RT-AC66U with Firmware 374.43_39E3j9527 ([Fork] Asuswrt-Merlin 374.43 LTS releases (V39E3)):

I have googled and found your old post from May 19, 2013. I have also found a few other posts on the net with the similar "problems" with RT-AC66U.
So, I think there is nothing to worry about as it seems that these are "common" messages for RT-AC66U and could be ignored.

Don't worry about it - not saying something is wrong...
