Like happens with fedora 19, it works the first time, but when you make it for second time, it don't hibernate/suspend.
I try to find tuxonice kernels but only i found for RHEL5 or many fedora.
Any other solution? In Arch it works perfect just with base kernel
Suspend/Hibernate not working properly
Re: Suspend/Hibernate not working properly
If you have an old AMD CPU you'll probably have trouble resuming from suspend (aka sleep) and hibernation. The CentOS devs have applied the fix for this to their "kernel-plus" kernel. To get this fix you simply need to use the CentOS 7 kernel-plus kernel.
