Ubuntu 18.04 kernel panic on shutdown

Question

I am having trouble when shutting down Dell Alienware Aurora R7 after installing ubuntu 18.04. The nvidia drivers were successfully installed.

I faced the same issue myself and found a solution. See my answer here for the instructions: https://unix.stackexchange.com/a/446913/52937 — Yurij, May 30 '18 at 13:30
@yttrium Could you copy-paste your answer from U&L to AU as the question might be closed because it's a bug... (Already upvoted over there, will do same here if you ping me) **;-)** — Fabby, Oct 24 '18 at 21:22

Copy-pasting answer from U&L as per people request

After reading kernel sources, I found a function we need to blacklist!

Thanks to Stephen Kitt for the hint about initcall_blacklist.

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.
Append blacklist string to the GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT="… initcall_blacklist=dw_i2c_init_driver".
Save the file, close the editor.
Run in the terminal: sudo update-grub.
Reboot and test!

I am using a Dell Aurora R7 w/ a Nvidia 1070Ti. I am running Kubuntu 18.04.2 on the 4.18.0 kernel and this worked for me. – user838494 Mar 23 '19 at 15:41
