Raising hand....me too!
I'm also using an eMMC Module (64 GB) on the Odroid C2.
It would be great if this issue could be fixed with a new image. I just made an entire backup of the boot folder after a fresh installation and try to replace the dtb directory content once I flash back the previous backup of the broken image (this wasn't successful in the first attempt but I give it another shot).
EDIT: Moved to a 32GB microSD for the moment until it is fixed. If I clone the microSD to the eMMC card it boots up fine but on the reboot it's broken again. So there is something happening (script at startup or on a regular shutdown) that messes things up.
