What is your graphics card? my is AMDnRadeon HD 5000/6000/7350/8350
Series, so one firmware-amd-graphics maybe can work here.

yeah, I have such dmesg after rebooting every time. But once it passed
the complaint, the whole system worked normal.
The log maybe from power issue with the graphics card.

In fact, the wiki you followed I think was some obscure. I am not sure
your u-boot-* file was put where. But
I remembered if putting them on SD and nvme separately and this caused
maintainance trouble: after upgrading kernel
need to copy from SD to nvme. So I just simple here: on nvme, there is
only rootfs; on sd card, there is only
u-boot-* file. it works! But if you enable to boot from onboard SPI
Flash as the wiki, you do not need sd at all maybe.
Here is my pre-built Unmatched Debian image(hope this helps):
https://github.com/yuzibo/Unmatched-Debian-image/releases/tag/0.0.2
Then dd these images into nvme and sd separately then the system
should work. On my system, there is no kernel parameters,
just:
rv@debci-01:~$ cat /proc/cmdline
root=/dev/nvme0n1p1 ro quiet
