I'm having the same problem in that during boot eth0 is first renamed em1 for one NIC and then eth0 for my second NIC is renamed p3p. Sometimes one is first and sometimes the other but the names always correspond with the correct address. Only one of them works, though.
I'm about to try adding /etc/udev/rules.d/70-persistent-net.rules and then modifying grub. My grub has a line:
GRUB_CMDLINE_LINUX_DEFAULT="text"
Which do I do, replace that line or add the new line?
