Hi,

something still seems strange.  I have ~/.ssh/id_rsa and 
~/.ssh/id_rsa.pub files.  I am able to log in just fine to other servers 
using the keygen information without stalling.  it is just two recently 
built servers out of about 10 that are displaying the stalling issue.

Here is from a server that works fine with no stall:

Welcome to FreeBSD!

Before seeking technical support, please use the following resources:

o  Security advisories and updated errata information for all releases are
   at http://www.FreeBSD.org/releases/ - always consult the ERRATA section
   for your release first as it's updated frequently.

o  The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
   along with the mailing lists, can be searched by going to
   http://www.FreeBSD.org/search/.  If the doc distribution has
   been installed, they're also available formatted in /usr/share/doc.

If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the questions@FreeBSD.org mailing list.  If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
man page.  If you are not familiar with man pages, type `man man'.

You may also use /stand/sysinstall to re-enter the installation and
configuration utility.  Edit /etc/motd to change this login announcement.
