I had similar issues when i installed Ubuntu i tried to boot ubuntu but it got hang because of ACPI error
i made acpi off so it can boot in but when i tried to shut down it got hand this time
Reason is simple
Its related to your graphic card
step 1:
i went through these proceess
->booted into system with acpi off from grub command
since i was not able to without doing so
step 2:
later when i got into ubuntu
i did
(this step neccessary or not i'm not sure, included it since i had followed it) i think its very necessary
->sudo apt-get update
->sudo apt-get upgrade
after doing this once you might hang but on restart you wont need acpi off
you can run ubntu without any hang during start splash screen or shutdown splash screen
