Hey

I have AXT1800
OpenWrt 21.02-SNAPSHOT r16399+164-c67509efd7
Kernel Version 4.4.60

Is that ok kernel constantly prints to logs:

This is almost certainly triggered by the snapshot firmware.
Snapshots (aka “nightly builds”) are untested, unfinished and buggy.

Your only option is to switch to the next snapshot firmware (the latest version is uploaded every night) or to revert to more stable firmware branches such as beta, rc or stable.
