450b SM event log special reset code

If customer power cycles this SM we get the following message in the event log instead of the usual power on reset message.

System Reset Exception – Special Reset Code 00000001 100F11EE 6FF07FF5 0 0 0 0 0 0 0

I see a similar post from back in 2019, but this is different hardware and much newer firmware. What does this mean?
