Interesting.  I don't have any enable_uart in my /boot/config.txt and my Pi-3 
is working as expected.

I installedjessie-lite a while ago.  It's been updated/upgraded regularly, so 
I think it's the latest mainline but not bleeding edge.  uname says the 
kernel is 4.4.9-v7+  That's ahead of Raspbian

Mine says
dtoverlay=pi3-disable-bt
dtoverlay=pps-gpio,gpiopin=4
