I'm having an issue with random stuck cpu's when trying to get Ubuntu 16.04LTS going on a Dell Alienware 15 R3. The computer does have the latest BIOS installed. What I've done outside of the base install:
Update the grub defaults in
/etc/default/grubto be:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nogpumanager acpi_osi=! acpi_osi=\"Windows 2013\""Install nvidia-378 driver from the
ppa:graphics-driverrepo, along with prime select and bumble. Set primary graphics to intel and verified that bumblebee is up and going successfully
When the system boots, it's stable - nothing seems to lockup. The problem is that sometimes when I try to boot the system, it will get setup on a CPU hang.
Any suggestions on what else needs to be adjusted or tweaked to get this going?

You may find your answer in this github link.
I noticed that you have written acpi_osi=\"Windows 2013\", while the one in the github link has "Windows 2009".
Now, I'm unsure if your problem is pertaining to the lspci or lshw, but it is worth a try to set up the grub options properly.
