Suspend is not supported. It works by luck or it does not work.

It's not a Kodi related issue, but a LibreElec one. It works just fine on an OpenElec build compiled from source, However (one of) the developers asked me to post LibreElec related queries for Kodi 17 in this particular thread because they only support the stable version of LibreElec there. Which is fine, I can all understand that but I would like to know where to report a bug whether it is a stable release or not, or do you suggest people give up reporting on in development releases?

TLDR: Not seeking for Kodi support, reporting a LibreElec issue here per request of their developers.

This is the right place to report issues with these test builds, the problem is that you were reporting an issue on the LE forum while using one of these test builds which are not supported on the LE forum. If you'd not posted details from these builds I wouldn't have asked you to post here.

Now that it's reported here, the support for suspend does appear to be somewhat hit & miss. I guess there's a number of factors to take into consideration - BIOS, kernel, drivers etc. - most of which are outside of LE's control, particularly BIOS. You could go back through the builds and identify which is the last to suspend/resume normally, chances are it broke with a new kernel.

Interesting that you say it works with OE compiled from source - is this current OE master (based on 4.6-rc6 kernel) or something older?
