Resolution (obtain from Nvidia Community Support)

Edit /etc/default/grub and append the preceding to GRUB_CMDLINE_LINUX_DEFAULT, for example:

GRUB_CMDLINE_LINUX_DEFAULT="systemd.log_default=debug  pci=realloc=off"

Update grub:

# update-grub

Reboot. After this the drivers load as expected, nvidia-smi produces results, the nvidia-persistenced service loads properly, etc.

After applied the resolution above, the A16 GPU can be see from nvidia-smi.
