I've just been testing by running "cat /dev/serial0".  No reason to start gpsd if I can't see the NMEA sentences coming across the serial port!

I just downloaded Raspian 9 Stretch, with the 4.14.98 kernel and it works correctly.

Similar dmesg output:

ttyS0 at MMIO 0x0 (irq=166, base_baud=31250000) is a 16550

My conclusion is that something changed between Stretch and Buster.

Blip, blop, bloop...
