One issue is that most of the persistent labeling schemes require an
initrd to interpret them. I'm using a super-simple initrd to just find the
first proper-looking partition and mount that, maybe I should put it
somewhere..

PARTUUID is interpreted directly by the kernel. (filesystem) UUID= does
require an initrd to map (but it's not complex if you put the blkid tool in
there and a shell, I believe).

Output blkid on my device

Because mmcblk0 is PARTUUID the same for all partitions, I have
decided that this path does not lead.
I used dracut to create initrd-next and heuréka - success.
Here is the result.

You were right. The name of the disk was overwritten.

I recompile the kernel again and add the firmware vic04_ucode.bin

Let me thank you, Mr Jon, Mikko, Stephen for your support.

Notice: I look forward to the driver support for the sata interface on
the jetson tx2.

Best regards
