So, I think in both cases, udev *is* using the 'path' rename policy. However, it seems that on *one* system, the kernel has a value for /sys/class/net/<iface>/phys_port_name, which results in the addition to the interface name.
Can you please run:
$ cat /sys/class/net/<iface>/phys_port_name
on each machine (with the correct interface name), and report back? Also, can you report the kernel versions (uname -r) from each machine?
My new suspicion is that you have a different/newer kernel on one machine, and that the network driver gained support for phys_port_name_show().
Thanks for the logs!
