@piter75 commited the emmc fix into Armbian and built Armbian 21.08.2 which is already available through the Armbian mirrors (via 'apt update && apt upgrade').   It is save to upgrade your Buster or Bullseye installation to Armbian 21.08.2 - but emmc read speed will be about 50% what it used to be.   You can roll back to the previous linux 5.10.43 kernel if you don't like that - just install those files with 'dpkg -i *.deb'.
