"Data buffer not 16 bytes aligned": What does it mean?

Installing and Using OpenWrt
1

Hi, I installed snapshot LEDE/OpenWrt on a Netgear R6220 a few days ago. It runs well!
However, I keep seeing messages like

[86362.896365] Data buffer not 16 bytes aligned: 86d0c318
[86362.912138] Data buffer not 16 bytes aligned: 86d0c538
[86362.929556] Data buffer not 16 bytes aligned: 86d0c038
[86362.943063] Data buffer not 16 bytes aligned: 86d0c008
[86362.983358] Data buffer not 16 bytes aligned: 86d0c198
[86362.995805] Data buffer not 16 bytes aligned: 86d0c3b8

[86363.024799] Data buffer not 16 bytes aligned: 86d0c198

I'm just curious: What do they mean? Should I worry about them?

I am running OpenWrt SNAPSHOT r5882-dd975d15a7 / LuCI Master (git-18.017.72947-08916f4) on a Netgear R6220 and see the same messages regularly. Anyway it runs rock solid since 76days.
Which snapshot are you running?
I hope one of the expert can also answer this question easily. Looking through the forum I learned that the "
Xiaomi WiFi Router 3G" has the same processor + WiFi chipset (Xiaomi WiFi Router 3G). What is needed to support the Netgear R6220 with one of the upcoming official LEDE/openwrt releases?

Yeah, runs quite stable here, too. I recently upgraded to OpenWrt SNAPSHOT r6878-4045080 / LuCI Master (git-18.133.37847-2f0f456).
My guess is that the message is merely an indication that the performance is not optimal. Something about the memory access being fastest when data is aligned to 16 byte boundaries... just a guess.
