Hello Pablo,

Well, it was running on an RPI-2, and was probably a bit older. I 
swapped it for an RPI-3, with this image: 
CentOS-Userland-7-armv7hl-Minimal-1708-RaspberryPi3.img.xz:

[root at seismo ~]# uname -a
Linux seismo 4.14.27-v7.1.el7 #1 SMP Mon Mar 19 20:03:06 UTC 2018 armv7l 
armv7l armv7l GNU/Linux

and that just seems to be working like expected.

Ron
