Hi,
So just to clarify, the issues you and other users are experiencing are:
1. When you run the command poweroff, the XU4 will not power back on again? Either using the power on button, or, physically reinserting the PSU?
2. When you physically remove the PSU without shutting down, the XU4 fails to power on again?
Can all users who have experienced these issue please list:
- The board revision number/dates on their XU3/4.
- Power supply used (eg 5v/6a)
- SD/EMMC card used and size.
- If you have time, please try installing the following image http://oph.mdrjr.net/meveric/images/Jessie/Debian-Jessie-1.0~RC2-20151123-XU3.img.xz, (username = root, pw = odroid) run apt-get update and apt-get dist-upgrade -y && reboot, then please try to replicate the power on issue you are experiencing (eg: Pull power plug and put back in again, or poweroff)
Also created a Git ticket so we can investigate this: https://github.com/Fourdee/DietPi/issues/558
