Kickstart hangs at dracut-initqueue (CentOS 7.2)

[therbur]

I have a Cobbler setup that loads a CentOS 5.7 OK.  I am trying to add a
CentOS 7.2 load.

It stops just after the line that shows:

... dracut-initqueue ...  Dload Upload Total Spent Left Speed

Actually, it doesn't stop, it just pauses a long time, then says dozens of
messages like:

... warning: dracut-initqueue timeout - starting timeout scripts

Then it comes to a "dracut>" prompt.  Doing "journalctl" as it suggests, I
don't see anything obvious that would tell me the actual problem.  Also
tried "cat /proc/cmdline" and it worked, didn't see anything unusual.

What is it looking for when it gets to the dracut-initqueue line?  What
are some possible causes/solutions?
