Artem,
Thanks for taking the time to look at this.

I'm not sure if I can share the image just yet.  What all would you
need?  vmlinuz, uImage, the config file?.

I've changed my test setup slightly since my initial post.  My test
setup now includes a Linux PC that is connected to an ethernet
controlled power switch
(http://www.controlanything.com/Relay/Relay/ethernet_relay_controllers)
that is powering my hardware.  I have a script that runs that sends a
command to the power switch to cut power, sleep for 2 seconds, then
re-apply power.  It then waits anywhere between 0 and 45 seconds
before cutting power again.

I've upgraded to linux-3.5.1 and I haven't started to run the test
again, but will pretty soon.
