>Synopsis: em0 does not get address from DHCP server in time
>Category: system amd64
>Environment:
System : OpenBSD 6.7
Details : OpenBSD 6.7-current (GENERIC.MP) #186: Thu May 14
00:13:53 MDT 2020
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
In recent snapshots, it seems that em0 sometimes does not get a link
and/or IP address from the DHCP server quick enough and the interface
is left without a proper IP address. This has the knock-on effect that
ntpd does not start properly, and, since it happened to the OpenBSD
machine running my local unbound, my home network was left without being
able to resolve local names, mount NFS shares, etc.
starting network
em0: no link......
em0: 192.168.1.60 lease accepted from 192.168.1.1 (74:83:c2:d6:b7:e8)
reordering libraries: done.
starting early daemons: syslogd pflogd unbound ntpd(failed).
[...]
Even though a lease is accepted, the IP address is not always given
to the actual em0 interface, and I have to log in as root on the
physical machine and run "sh /etc/netstart" and start/restart the needed
services.
This may or may not be related to

>How-To-Repeat:
Reboot, be unlucky. Seems to happen more or less consistently after
sysupgrade.
>Fix:
Reboot, be lucky.
