it looks like I can, since yum is keeping 3 Kernels, (right now we are back to prod but I can test later). From what you posted and what I have read I assume booting temporarly from the v7 kernel should get me back up and running?

[root@gateway ~]# rpm -q kernel
kernel-3.10.0-327.3.1.el7.x86_64
kernel-3.10.0-327.36.3.v7.x86_64
kernel-3.10.0-514.6.1.el7.x86_64
[root@gateway ~]# uname -a
Linux removed.name.local 3.10.0-514.6.1.el7.x86_64
