Try adding a resistor, 47 to 100 ohms, in series with the MOSFET gate to decouple the gate capacitance from the processor output. Connect it between the pulldown resistor and gate.

I have also seen the start-up step phenomenon you described. When driving an inductive load, like your relay coil, I ...

For testing, I'm echoing characters received on COM1 to COM0.
I have a terminal program connected to COM0.


char serByte = sgetchar( 1 ); /* wait for received character */

Early in main, before anything is sent to the LCD, I set the following:
