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.
