pogoplug v4 shutdown problem

[brainticket]

I have successfully installed a system to my pogoplug v4 by following the provided instructions which were straightforward and helpful. I can also /sbin/reboot with no problems.
However when I use shutdown -h now, the system shuts down but I can never boot it up again. I get a constantly blinking green light when I try to power up. I have done this twice now, each time having to revert and reinstall.

Surely there is a way to shut down my system cleanly. What am I doing wrong? I found nothing on these forums about this.
Thanks for any suggestions.

My v4 is the A3 model. I tried reverting to shipping os and reinstalling again. This worked fine. However when I power cycle the system never comes up again. The light on the usb stick blinks a few times. The blinking green light on the v4 continues. I tried power cycling multiple times. There is no entry on my router DHCP table.

A note in the install guide says that soft reboots occasionally fail. This has not happened to me and I don't think is related.

This might relate to this post or even this post. I'll have to figure out what the significance of rootfs is. I am pretty new to linux
I am using a Patriot Rage 8GB quad channel usb stick. I thought I'd try getting the fastest usb2 stick I could find. Maybe I should try using a cheapie instead, in case the system is having problems initialising this stick.

For anyone who is interested, I finally got this working using a SATA boot disk. I still can't power up from a usb memory stick. If anyone is able to do this, I would be interested to learn how.

I have one of mine running on a SATA and another running on a SanDisk Cruzer Fit 16 GB which is small enough to fit inside with the lid on (http://www.amazon.com/dp/B005FYNSZA) This second one is on my workbench and is for having a native ARM Linux I can write to USB and SD easily and test things without having to walk back and forth to the Raspberry Pi or Pogoplug in the other room. It is likely that when I get my second RPi this week, I will use this Plug to write its SD cards for boot instead of fiddling with the Mac or Linux laptops.

I installed it from stock using the instructions - this wasn't the initial USB stick, I actually used an 8GB Toshiba stick while I was waiting for this one to arrive, then I copied the files over using rsync (using this method I think: https://wiki.archlinux.org/index.php/Fu ... with_rsync)
