I usually use 'biosdevname=0' on the GRUB kernel command line to get eth* 
names back in all cases. As in:

# grep bios /boot/grub/grub.conf
         kernel /vmlinuz-2.6.32-431.11.2.el6.x86_64 ro 
root=/dev/rootdg/lv_root rd_LVM_LV=rootdg/lv_swap rd_NO_LUKS LANG=C 
KEYBOARDTYPE=pc KEYTABLE=us-acentos rd_LVM_LV=rootdg/lv_root rd_NO_MD 
rd_NO_DM SYSFONT=latarcyrheb-sun16 crashkernel=auto intel_iommu=on 
swiotlb=65536 pcie_aspm=off elevator=deadline nouveau.modeset=0 
rdblacklist=nouveau biosdevname=0
                     ^^^^^^^^^^^^^^

I hope this helps,

Vincent

They cannot scare me with their empty spaces
Between stars - on stars where no human race is
I have it in me so much nearer home
To scare myself with my own desert places.       - Robert Frost
