Attached is the screen after 2 iterations of the error. That error repeats itself maybe 10 times (not sure how many). But it does EVENTUALLY boot after like 5 minutes maybe.
What is causing this. I've searched for the same error and see a few people with similar issues but no resolution.
The computer this is running off of is a fitlet2 (https://fit-iot.com/web/products/fitlet2/) with the following specs:
fitlet2 - build-to-order
CPU: Atom x7-E3950 [CE3950]
RAM: 4 GB [D4] $34.80
TPM: Not installed
Storage: M.2 SATA 32 GB [M32S]

Top cover: Standard top-cover
Temperature range: Commercial temperature range 0°C to 45°C
DC input: Standard DC input range 7V - 20V
It's worth noting again that OPNSense works, entirely, in this state. But startup takes about 20x longer than it should because it keeps waiting for whatever that is.
OPNSense version on that is 22.1.
In case anyone in the future finds it, this worked for me.
