<pre>This remember me a old FIXED bug but with forcedeth <a class="bz_bug_link

title="RESOLVED FIXED - systemd-networkd: could not bring up interface: Connection timed out (randomly)"
href="show_bug.cgi?id=75871">Bug 75871</a>[#1] that I
reported.
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). This is on Arch Linux with stock kernel.
While trying to debug the issue, I discovered a workaround, if I enable
log-level debug in networkd, interface always gets initialized on boot. (The
same workaround used in 75871)
