Mmmmm ..something is using the serial interface.

Can you try killing gpsd process and then run the command again, no with extra debugging "-D 6".. please show me the first few lines.

sudo killall gpsd
gpsmon /dev/serial0 -D 6

please show me the contents of /boot/cmdline.txt

please show me the output of ls -l /dev/serial*
