[evlatests] power outage

[Mike Revnell]

In case word hasn't gotten out yet Jim Jackson tells me that he thinks 
he's identified what's going on with the DTS modules failing like this. A 
fix is on the way.

This doesn't explain why the batteries don't carry the system through 
though.

It seems that it takes the network switch in the antenna a good two 
minutes to reboot. The MIBs give up on getting an IP address much quicker. 
Thus they never get initialized.

Once this fix is adequately tested we'll push the new images out to the 
MIBs.

Of course, Murphy may have more to say on this.
