[Solved] Reboot stalls on ODROID-X2

[gangtrashsta]

I am looking for help with getting the ODROID-X2 running Arch Linux to reboot correctly.

I wrote a fresh image of Arch Linux to eMMC card and connected it to ODROID-X2, noticed reboot always hangs on
[ OK ] Reached target Shutdown.
Reboot is quiet vital for me since I am going to set this up in a location out of my physical reach and will need to manage it remotely.

I am fairly new to Arch Linux so I would need help with most debugging processes you may ask me to do, please type example commands with each suggestion you give.

Below is the output of the UART module connected to ODROID-X2 with a fresh image of Arch Linux written to an eMMC card, The results are the same before and after I update packages.

Found a solution.
When the ODROID-X2 is booted in eMMC mode, rebooting will always fail if there is no SD card found that ODROID-X2

Solution: Leave any functional SD card plugged into the ODROID-X2, doesn't matter if it is empty or being used by the ODROID-X2.

Notes: This rebooting problem does not happen when the ODROID-X2 is booted in SD mode.

Quick question...when booting from eMMC, do you have the jumper for SD/eMMC on the proper position?
