This bug now appears to be resolved with the most recent build of the armhf installer, dated 2021-12-13 15:23, and located at: https://deb.debian.org/debian/dists/stable/main/installer-armhf/current/images/hd-media/SD-card-images/
Installer Files: firmware.BeagleBoneBlack.img.gz partition.img.gz Note: The previous (broken) version of these files had timestamps of 2021-10-04 08:07. Note further, the ethernet module is not working correctly in this build on BeagleBone Black. I will open a separate bug report for this issue. Dave Kaiser
