OpenWrt 19.07.0 does not work on Turris Omnia

LAN port with VLAN untagged + tagged. The full history: DSA switch port vlan tagging - untagging

I have the same set of errors on a different router (UniElec 7623-06) which has eMMC installed and mmcblk0p1 has vfat type. I was looking for quite long any explanation or answer are these messages something to be worried about. Do you have any additional info about this?
