Hi Lava users,

I just updated lava from 2016.12 to 2017.6-1. And I found my health-check job failed(uncomplete) after the update.

Here is the result logs before:

and after:

I checked the log and think the cause for the issue is:

```
case: job
definition: lava
error_msg: constants section not present in the device config.
error_type: Configuration
result: fail

```

What I have done:

* Try to find the "constants section" with no luck.

* Looked at the logs in /var/lava-server/ and didn't find the log specific for the reason of this.

* Asked IRC channel and ask, answered by codehelp(thanks:)). Then tried to replace my device-type config in /etc/lava-server/dispatcher-config/device-types with x86.jinja2 and the error message is the same.

Any input would by much appreciated, thank you.

Regards,
