This seems to happen everytime I boot the machine (t8103).
It’s not critical and works well otherwise but just in case it’s something to track I’m creating this issue here.

Feel free to close it if it’s not the right place for this. I can also link the entire dmesg output if needed.

This was a u-boot bug and should be fixed now.
