[Arm-dev] That was exciting! :-/

Ian, that is definitely one of the things that changed, and executing 
extlinux should fix your issue.
Maybe there is a timing problem between the installation of 
extlinux-bootloader and the new kernel, but it should only affect those 
who didn't have exlinux-bootloader installed.
Please add fdtdir /dtb-4.14.28-201.el7.centos.armv7hl and fdtdir 
/dtb-4.9.75-204.el7.centos.armv7hl to both kernels respectively.
If that works, I'll try to add a note to with some recommendations.

Thanks.
Pablo.
