Red Hat Bugzilla – Bug 1476885
power off does not work on iMac
Last modified: 2017-08-01 18:12:46 EDT
Description of problem:
Selecting "power off" from GUI environment causes machine to restart after several minutes.
Version-Release number of selected component (if applicable):
[rc@localhost ~]$ uname -a
Linux localhost.localdomain 4.11.11-300.fc26.x86_64 #1 SMP Mon Jul 17 16:32:11 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
100% of the time following steps below.
Steps to Reproduce:
1. Click "power button" icon in GNOME GUI
2. Select "Power Off" in resulting dialog box.
The machine starts the shutdown process. The last entry on the screen trace says, "reached target reboot: Poweroff". a minute or two later the screen goes dark, and a few more seconds later the boot screen appears prompting for kernel to load.
Same thing happens using poweroff -f
Machine shuts down and powers off
HW environment: Late model iMac

I've seen other bug reports with similar problems on non-Apple hardware, #1365352 comes very close to what I am seeing. But that was on F24 several months ago.
