Odroid N2+ and FANTEC QB-35US3-6G: Restart or Reboot Takes FOREVER or hangs

Hey guys. I have an N2+ and a FANTEC QB-35US3-6G with 4 hard drives. 1x12TB, 1x8TB, 2x4TB. Whenever I have to reboot or restart Kodi, the N2+ stays forever frozen-like. Sometimes after 10 minutes, I disconnect it and back on.

What could be the problem? Thanks.

Post some logs for start.

Or in SSH

journalctl -l | paste
dmesg | paste
