Power Issue (involving Servo Motor)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Turn on RPi
2. Plug in Servo
3. Issue Arises

What is the expected output? What do you see instead?
Expected output is no errors.  What we get instead is that "eth0 is dead".

The cause of this problem is that the 5 volt rail is not providing 5 volts to 
the 3v3 rail which then causes a drop on the 3v3 rail which then causes eth0 to 
crash.

See: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=6&t=4828

Solution to this problem is the power board that I asked you to build... As 
long as you have the 5v@1A regulator feeding the Raspberry Pi and the 5v@3A one 
feeding the Servo things should be all fine :D.

The other alternative is that you have the power board with an extra ground 
header so that you can directly feed the servo 6 volts, which it can use (It 
rated to 7.2 volts).

Please deal with issue WITH-IN 24 HOURS!!!
