Rock64 configuration fails to boot for main 22c4ab6cb015 but worked for main 06bd74e1e39c (Nov 21): e.MMC mishandled?

Attempting to update to:

resulted in boot failure (showing some boot -v output):

Nothing more after that.

An older kernel (1400042) that happened to be available boots
the same configuration when used instead (same world) . . .

(I'll stop with that.)

So I end up with a 1400042 kernel and a 1400043 world in order to
boot.

The e.MMC has only:

# ls -FTld *
-r--r--r--   1 root  wheel   6170 Feb  1 04:48:34 2020 COPYRIGHT
drwxr-xr-x  23 root  wheel   1536 Dec  8 20:18:34 2021 boot/
drwxr-xr-x   2 root  wheel    512 Apr 26 14:39:22 2020 etc/
drwx------   2 root  wheel  33280 Nov 27 09:46:08 2019 lost+found/

where the etc/ has only:

# find etc/ -print
etc/
etc/hostid

World comes from the USB3 SSD that is attached but the kernel
comes from the e.MMC instead. (The kernel can deal with the
USB3 SSD just fine, unlike the U-Boot that is involved.)
