Just wondering if it would be wise to upgrade to this on the Core? https://libreelec.tv/2017/03/libreelec-krypton-v8-0-1-mr/
You can choose a version for the Core from the drop down menu.
I may be missing something on those pages but I see no mention of the Core governer being changed to 'hotplug'.
Since manually changing (following some excellent advice in this forum) from 'ondemand' to 'hotplug' I've had ZERO issues in LE8.0.0 and don't want to risk updating if there hasn't been an 'official' fix.
