I built a system for a frien on Pi2 and upward (including the Pi3b+), and
they all boot with the PRi2 image using a kernel that is 2 years old.

I think what might be going on with MythTV hiccup'ing is that the aarch64
architecture that the Pi3+ is capable is just recently being adopted
everywhere.  I woiuld imagine that may be the difference between versions
(not sure - I ship Arch rather than Raspbian on them).  Arch offers the
aarch64 version, but it is still missing a lot of functionality and DTS
capabilities.

Of course, I may be way off - I did not even go look at the stretch
downloads - just throwing it out there.  There is definitely not a brand
new kernel needed though - they still run just fine with the old 32 bit
kernal and userland as well.  The 64 bit kernels are definitely not prime
time though (aarch64 vs armv7h).
