Fresh from Suricata training in Sunnyvale CA (Thanks Peter and Eric!) and looking to upgrade the kernel on my CentOS hosts.

Assuming I follow the procedure of adding the elrepo repo and running the kernel upgrade -

1. What are the possible risks - what could break?
2. Following upgrade to the kernel - are there any other requirements other than changing the default kernel to boot in GRUB?
3. Which version is recommended?  4.7, 4.9 ?
