After upgrading to kernel version 4.15 my computer can no longer shutdown
properly.

Reproducible: Always

Steps to Reproduce:
1. running kernel 4.14
2. sudo zypper dup (upgrade to 4.15)
3. reboot into 4.15
4. shutdown/reboot
Actual Results:  
Computer freezes on tty screen during shutdown process

Expected Results:  
Shutdown normally

After initiating shutdown the session logs out and I am shown the tty log in
screen normally that would last a few seconds but it now freezes on the tty
screen and the computer gets very hot and the fans increase a lot. I have
waited an hour to see if it is just doing something like rebuilding a kernel
module.
Selecting the 4.14 kernel from grub does not have this issue.

About half the time after attempting to reboot with the 4.15 kernel my UEFI
settings in BIOS change. Unsure if related.
