Hi,
Each time I turn off Fedora 24, I get the following message about 50
times printed in the console:
Kernel not configured for semaphores (System V IPC). Not using udev
synchronisation code.
device-mapper: remove ioctl on fedora_alpha-root failed: Device or resource busy
Command failed
What does that mean?

It means you should follow this bugzilla....

I am inclined to believe this bug might not be related to the OP's
problem - At least not the incarnation, I am facing ;)
What I am seeing on several machines, is larger series of the error
message above rushing through very rapidly (<< 1sec) upon each shutdown
on several machine, but so far I have not been experiencing shutdown
hangers.
