I have only one configuration file for em1 but I doubt it's related to this issue. Here's the udev dmesg output:

[    4.429169] systemd-udevd[302]: renamed network interface eth1 to p2p2
[    4.441210] systemd-udevd[304]: renamed network interface eth0 to p2p1
[    4.446207] systemd-udevd[306]: renamed network interface eth6 to p1p3
[    4.457198] systemd-udevd[305]: renamed network interface eth3 to p2p3
[    4.467193] systemd-udevd[311]: renamed network interface eth5 to p1p2
[    4.480199] systemd-udevd[308]: renamed network interface eth4 to p1p1
[    4.480247] systemd-udevd[309]: Tried to rename network interface eth2, but the target name p2p3 already exists! The names that udev rules assign to network interfaces must be changed. Avoid names that collide with kernel created ones. A workaround will be attempted now, but this WILL BREAK in a future release! See https://bugs.freedesktop.org/show_bug.cgi?id=56929#c3
[    4.491179] systemd-udevd[313]: renamed network interface eth7 to p1p4
[    4.502116] systemd-udevd[309]: renamed network interface eth2 to rename8
