I've had the same thing happen here with RELENG_5_1.
When you have managed to log in, run "sysctl -a" and see if that one also
hangs (it's being run as part of the initrandom-stuff).
If "sysctl -a" hangs too, you might run "top" to see that "sysctl -a"
consumes all your CPU. You can kill sysctl with CTRL-C or a kill-command.
My solution was to go back to the GENERIC kernel and just add the three
IPFILTER-options I needed there. With my custom kernel I'd see this problem.
I saw this problem 2-3 days ago and haven't had time to look deeper into
WHY it's failing (or filing a PR) since I've also had to actually get
FreeBSD installed on that server.
If anyone's interested, here's some information:
When running "sysctl -a" lots of output is shown, but then it hangs. Here
are the last few lines it shows:
[...]
net.inet.ipf.fr_authused: 0
net.inet.ipf.fr_defaultauthage: 600
net.inet.ipf.fr_chksrc: 0
net.inet.ipf.ippr_ftp_pasvonly: 0
net.inet.ipf.fr_minttl: 3
net.inet.ipf.fr_minttllog: 1

Compiled sysctl with "DEBUG_FLAGS" set (but they might not be set
correctly), started that sysctl, killed it with "kill -SEGV" when it is
looping to produce sysctl.core:

I haven't had time to experiment with this kernel config just yet so I'm
not sure exactly what can be wrong.
