The stuff I do is only feasible with enterprise linux (Red Hat, Suse). Now most people in this field would use Centos variant. Latest version only has 3.10 kernel.
I can use Oracle Linux instead and get 4.1 kernel. The best possible is kernel 4.4 if I use Suse Leap .
Are any of these able to properly support Zen/Threadripper/Epyc?
