I'll note that my testing that Mike mentioned was without any USB devices
being plugged into any USB port: Just Serial console, Ethernet connection,
power supply, and the fan's power-pin connections. Nothing else connected.

As for my context's power supply: 5.1V 3.5A (CanaKit model
DCAR-RSP-3A5C) .

The same power supply was used with the 8 GiByte Rev 1.5 "C0T"
RPi4B for its test --and the 8 GiByte Rev 1.4 "B0T" RPi4B that
I later tested but did not report to Mike.

Only the old 4 GiByte Rev 1.1 RPi4B's failed to boot 14.1.

All RPi4B's were using the same microsd card boot media that
was produced by downloading the .xz and then expanding it and
the dd'ing it to the microsd card. No modifications.
