right. Well, those network services should only (re)start once the
network link is up.

But as to why the network link is taking a while to come up; I'm not sure.

The device timeouts are a known race. It's not indicative that a
device timeout actually did occur. Fixing the watchdog to be actually
correct is on my TODO list but it's fallen behind in priority.

I have a feeling that the probe requests aren't being given enough
time to go out. Would you mind trying to change the eventtimer /
timesource (sysctl kern.eventtimer and sysctl kern.timecounter); see
if that helps things along?

Thanks,

	Sure, I have no problem making a change. I placed the available options 
for my system below. Which do you prefer I use for this test?
