I'm not sure this is a bug so much as new technology being implemented
inconsistently. I suspect the problem is due to an Replay Protected
Memory Block

My HP stream has an RPMB
dmesg | grep mmc

[ 2.319490] mmcblk0rpmb: mmc0:0001 DF4032 partition 3 4.00 MiB, chardev

I read, but cannot confirm, that this area is messy with 3 different use
cases. Linux/FreeBSD essentially code the 3 possibilities.
