Dmesg log is too noisy

Can anyone tells me the reason of log below?

$ uname -r
4.4.154-78-rockchip-00017-g625c2b2

btw, wifi is working well

Thanks!

It seems not wifi related. It seems it’s the issue of arm64 running 32bit applications. Which os are your running?

Oh, really?
It’s running on Debian.
