With the machine up, running and idling I see 5.06 volts.
When shutdown -r is issued on the console the voltage
rises to 5.13 with the red power LED on steadily.
Meanwhile, the Pi reports
root@www:~ # shutdown -r now
Shutdown NOW!
shutdown: [pid 1420]

This doesn't look like a power supply problem to me.
The Pi gets far enough to spin up the disk, find
u-boot and run it. Only then does it run into trouble.
The error messages that are presented are always so.
Perhaps they're symptoms of some other, underlying,
problems?
Thanks for reading!
