Do you have the EC/AP consoles?

Also the servo v4 console would probably be useful

power info change during Servo V4 passthrough?

Is it only reproducible with servo_v4? 

I don't think we want to test scarlet using previous version of servos. 

So yes, it happens to Servo V4 type C. 

Well, dive deep, looks like the devices reboot itself even the charger directly plugged in. 

Interesting, can you try another unit? Is this issue reproducible on every unit?

This isn't the sort of problem that englab-sys-cros@ deals with,
and anyway, haoweiw@ is out on leave.

nsanders@ can you find someone to figure out why scarlet is having
so much trouble with servo repair?

As per #6 it appears that userspace (autotest?) is requesting a reboot. 
Can you check the system logs when this occurs and see what autotest is doing?

https://cs/chromeos_public/src/platform2/power_manager/docs/shutdown.md?l=83
> In the above case, `not-via-powerd` indicates that this clean reboot was
> initiated by the `reboot` command being run directly 

From the product side, we'd need DUT EC and system logs to diagnose if there's anything unexpected going on here. 

I thought that this was referring to a DUT that is just rebooting by itself and not because Autotest is running against it?

It reboots unexpectedly in the lab, but the logs above suggest someone is unexpectedly calling "reboot" on the commandline. That indicates either: 

1) autotest is calling "reboot" unexpectedly due to some bug

2) The logs above don't represent the failure, and are logs from expected reboots. So we'd need logs of an unexpected reboot to diagnose.

Okay.  I'm going to need at least a hostname so I know which DUT to look at (or are all scarlet DUTs affected?)

You can use chromeos2-row1-rack11-host19
