I did a yum update so I am running on most recent stuff. Did a poweroff
and pressed the power button. The keyboard was unresponsive. I did a
poweroff via the serial console then unplugged the power, plugged back
in, and the system came up and I could log via the kybd/monitor. I then
just let the system sit and here is what I see in the message log:

37 minutes? I am sure there is some basis for this.
Of course the keyboard is unresponsive and the monitor is blanked.
Powering the testbed down for the night.

More testing. Seems the problem is more in the USB support. I am
running now with a real USB kybd and mouse, and just left the system
alone and no response on the keyboard or mouse. Looking at the serial
console I see:
# [ 3125.892236] usb 2-1: USB disconnect, device number 3
[ 3125.897847] usb 1-1: USB disconnect, device number 4
I did not do anything with the devices. Just left them idle.
