Details

Description: There is some kind of race condition with new systemd-networkd (219-5) because network interface (driver r8169), randomly does no get initialized on boot (no ip addr, no link up).
This at least happens with linux-4.0-2, no issue under 3.14.39-1. No issue with systemd-218-2 at all (3.14/4.0)

While trying to debug the issue, I discovered a workaround, if I enable log-level debug in networkd, interface always gets initialized on boot.

Additional info:

linux-4.0-2
