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! -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)1 8394 5849 http://www.math-info.univ-paris5.fr/~patte
