Hi everyone from Argentina!
Sorry for me english.
I need open the UART Serial port, disabled by default on RPI3 Volumio. Is for use an LCD 16x2 display : sparkfun.com/products/9395
When i try to open the “enable_uart=1” on /boot/config.txt, after reboot, the system dont boot.
There is a bug with Serial port?
Regards and thank you!
I’ve got the same display and could not get it to work with volumio.
Does anyone have any suggestions?

You need to remove the line kgdboc=ttyS0,115200 from cmdline.txt in /boot/. It turns off debugging over serial.
My guess it’s leftover from devs debugging over serial, let’s hope it gets removed in future versions.
