I tried this today and it failed! No reboot at all: computer stays alive
with a black screen and fan running.

I installed the last kernel available for fedora 24 (4.8.16). When I do
not work with computer (ie. Just start it, log-in and shutdown) the
computer shutdowns normaly. If I do something (read my mail, open a text
file...) the computer is unable to shutdown. Conclusion: a computer is
not made forworking! Just have it, start it and stare at your background
image (and do not change it, or you will be unable to shut it down!).


Chris Murphy says that it is a "regression". OK! So on fedora 27, the
system will be unable to even start!
