Now that I have webui displaying telemetry for multiple PMBus devices, I =
want to solve a power supply problem.

After boot, all PMBus devices have their power turned off via an =
OPERATION command. This happens about 10-20 seconds after boot =
completes. There is a message printed saying it is disabling them, and =
one line per action. Like:

VOUT 1: disabling

Where VOUT 1 does not match the name of the rails in the config files =
with the name and limits. It seems like a more generic term indicating =
voltage.

These devices are in the device tree and have hwmon running.

What service would be capable of shutting off the supplies? It would =
have to be able to discover them, perhaps by device tree, then issue =
standard PMBus commands.

Note: the Phosphor System Manager service fails at start up. I don=E2=80=99=
t know if this matters, I was going to figure out what it does later.
