ssh connection over ethernet to beaglebone takes forever

Hello all,
I’m using my beaglebone for some time now, usually I connect via ssh over ethernet from my PC and it was working fine.
Suddenly after a beaglebone reboot I can no longer connect to the beaglebone via ssh, it gets stuck before asking the password, no errors, nothing. This is the debug output:

$ ssh -vvv root@192.168.0.13

OpenSSH_6.6.1, OpenSSL 1.0.1h 5 Jun 2014

and then it just sits forever…
anyone has experienced this?

I’m using the Angstrom distro
uname -a
Linux Beaglebone 3.8.13 #1 SMP Wed Sep 4 09:09:32 CEST 2013 armv7l GNU/Linux

thanks in advance, greetings
