Ubuntu 16.04 hangs on reached target shutdown/restart

Question

Ubuntu 16.04 hangs on shutdown/restart I encountered this problem before but by editing the line in the /etc/default/grub from

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

and run

update-grub

fixes the problem.

But after doing some heavy tasks (like web development) my laptop still hangs on shutdown/restart.

But doing some normal tasks like web browsing my device can shut and restart normally. Any suggestions?

UPDATE: There is a time that my laptop hangs on here: [ OK ] Reached target shutdown [ 6431.968956 ] xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead [ 6431.971151 ] xhci_hcd 0000:00:14.0:HC died; cleaning up [ 6431.975210 ] reboot: Power down

After reinstalling Ubuntu on my laptop. I found the best way to avoid this problem. Make sure that when you install Ubuntu you must be connected to the internet so that Ubuntu will fully detect your hardware.
