hang after (re)boot.

Sufficiently modern Ubuntu does not use U-Boot by
default, at least for server builds.

ubuntu-22.04.1-preinstalled-server-arm64+raspi.img
has:

# more /mnt/config.txt=20
[all]
kernel=3Dvmlinuz
. . .

where vmlinux is seen as:

/mnt/vmlinuz

No use of U-Boot: direct booting of vmlinux via
the RPi* firmware's ability to do so.

They do provide uboot_rpi_*.bin 's for folks that
want to change to use such:

/mnt/uboot_rpi_3.bin
/mnt/uboot_rpi_4.bin
/mnt/uboot_rpi_arm64.bin

But the supplied config.txt makes no mention of any
uboot*.bin and things have to be changed to cause
a uboot_rpi_*.bin to be involved.
