Deepin Linux stuck on shutdown

Sometime my laptop successfully shutdown but sometimes no, it stuck on Deepin Linux Logo. After edit quiet splash to acpi=force in /etc/default/grub I can figure out my problem is stuck exactly at Stopping Disk. Here is /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="acpi=force" GRUB_DEFAULT="0" GRUB_DISTRIBUTOR="/usr/bin/lsb_release -d -s 2>/dev/null || echo Debian" GRUB_GFXMODE="1366x768" GRUB_TIMEOUT="5" Here is the image How I can diagnose what causing this stuck problem, and how I can fix it? Thanks in advance.
