I just installed 16.04 LTS on my new desktop, Dell Alienware Aurora R7, with i7-8700K, 32GB RAM, SSD(SM961 NVMe SSD) and 1080TI.
So far, everything works ok except I get a kernel panic when I try to shutdown (reboot works ok).
How can I avoid that?

I was actually looking into this due to the fact that I might get the same system.
There was a previous question for this situation for which an answer mentioned choosing a previous kernel version. That might solve it: Ubuntu 16.04 LTS IRQ kernel panic at shutdown - Alienware R7 desktop
BTW did you try the system with the latest non-LTS version of Ubuntu? That could also work.
On my Dell Alienware 17R3 with Samsung Pro 960 NVMe SSD I had a problem suspending/resuming lockup fixed by editing /etc/default/grub and adding the parameter acpiphp.disable=1 to the line containing:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Afterwards it looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpiphp.disable=1"
Save the file. Next update /boot/grub.cfg and generate a new initrd.img with the command:
sudo update-grub
Finally reboot and test.
I don't have the PM961, but rather the 960 Pro so haven't experienced your issue. If none of the other answers or comments help one last thing you could try is:
nvme_core.default_ps_max_latency_us=5500
parameter in /etc/default/grub LINUX kernel argument list. I just found this in Arch Linux. There are other steps you may wish to investigate in the link.
I have an Alienware Aurora R7/0VDT73, BIOS 1.0.11. The system crashed on shutdown because of IRQ issues on a built-in-module (i2c-designware-core).
I solved this by editing the file /etc/default/grub and adding the kernel option noapic, to this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet noapic splash"
After that you should also launch the command:
sudo update-grub
Now my system shuts down without any problem.
How I solved this issue!
Add initcall_blacklist=dw_i2c_init_driver to the kernel command line. This works for me on kernel 4.15.0+.
For anyone else who'll find this answer. You can do it by editing /etc/default/grub:
Run in the terminal: sudo -H gedit /etc/default/grub.
(if you don't have gedit installed use your favorite text editor or "sudo apt install gedit" without quotes)
Append blacklist string to the GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT="quiet initcall_blacklist=dw_i2c_init_driver".
Save the file, close the editor.
Run in the terminal: sudo update-grub.
Reboot and test!
