Description of problem:

Shutting down Fedora 27 on my MacBook Pro 15" 2015 produces a number of errors about the kernel not being configured for semaphores that scroll by.

These kind of errors detract from the user experience on Fedora.

Screenshots and screenvids of the error messages are attached.

Version: Kernel 4.14.18-300

How reproducible: Unknown.

Steps to Reproduce:
1. Install Fedora 27 on MacBook Pro 15" 2015.
2. Update to latest kernel, currently version 4.14.18-300.
3. Shut down.

Actual results:

No error messages would appear on shut down.

Expected results:

A number of errors about the kernel not being configured for semaphores that scroll by.
