Black oil after nearly 10k is fairly acceptable I'd say.
You could have a faulty oil pressure sensor.
As Dan said you could do with finding out exactly how much oil is in it. That much of an overfill could knacker a cat which might explain the smoke.
Could be something relatively minor or catastrophic. ....you need to do some investigation first.
Also worth putting a small cap of the dropped oil under a light and hold a magnet near the surface to check for metal swarf
