Boot Problems Pogoplug E02 (no replies)

Hello guys,

I have run into a problem with my Pogoplug. Until yesterday I was running the Arch Linux build which worked perfectly for me. But yesterday I tried to reboot and now I can't ssh into my system anymore.
So I started to reinstall Arch with these instructions: http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray.
The installation works flawlessly but after "/sbin/reboot/" I am not able to get a ping from the Pogoplug.

I also activated netconsole and it gives me the following output:
