Reboot don't work ax1800 Flint

Hey i don’t understand why, but reboot in my case don’t work, from GUI or from Luci, or ssh. I try reflash firmware, reset firmware but its don’t work, some time randomly its works but i don’t understand any patterns. I use firmware in stock just install 3 packages for smb-luci, mc, htop.
Firmware: Version4.1.0
Try beta firmware but have same issues.

If not install that 3 packages, will reboot work?
Please provide log for analysis.
