Hi Marc,

Glad that it works. So I'll probably sign/release that kernel in the
updates dir, but it the previous image doesn't even boot, that means we
need to generate an updated one that would support both rpi2/rpi3/rpi3b+
and not wait for 7.5.18xx release, as I guess some people will try to
use the rpi3B+ model before that :) (as you just did)

Have you tested that wifi works ?

For irc, yes, we have #centos-arm  .. :-)

PS : I have ordered myself a pi3b+ board that should arrive next week to
also test it.
