    Parallelism might be the issue. In the past, when the first
interface was discovered by the kernel and named eth0, then Udev would
immediately rename it, either to the same name if it matches the rule,
or to ethX which still doesn't exist, then freeing the name eth0, and so
on. The problem may now be that two interfaces are discovered
simultaneously.
