Issue reproduced 100% reliably, even within sysinstall.

ISO image used:

ftp://ftp4.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/8.4/FreeBSD-8.4-RC3-i386-disc1.iso

I just chose to Configure the system, selected Networking, chose NO to
the IPv6 configuration choice, and YES to the DHCP configuration choice,
then hit Alt-F2 to watch relevant output.

This was the result:

http://imgbin.org/index.php?page=image&id=13718

...with the fxp0 physif up/down messages continuing indefinitely.

fxp0 on the system is the Intel 82559.  Shot of console's dmesg:

http://imgbin.org/index.php?page=image&id=13720

Nothing is connected to fxp1.

Key points for those asking me to help debug:

- I only have VGA console on this box
- I do not have an IDE hard disk of any sort for temporary OS
  installation, setup, kernel testing, etc..
- The system cannot boot USB media of any sort, so memsticks are out
- The ATAPI drive is CD-only; there is no DVD support, so there's no
  easy way to get a "real" shell with full utilities (i.e. "Fixit")

So if someone wants to take a stab at this, they'll need to do so and
make me an ISO.  Sorry that I can't make things easier.  :-(

This definitely needs to get fixed before 8.4-RELEASE.
