I've got a fresh CentOS 7 test machine, fully patched. The command:
shutdown -h now
surprisingly does not halt the machine. Instead it reboots it. WTF?
I found the following Debian discussion which seems to be the same issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766338
However, removing kexec-tools in this case did not solve the problem. Nor does "systemctl poweroff" work.
Does anyone else see this? No, nothing is filed in bugzilla yet.

I've seen systems with broken ACPI BIOS support auto-restart on a shutdown. sometimes the behavior can be modified with a BIOS option.

same here, using a "ASUS All Series/H97M-PLUS, BIOS 2305 10/09/2014" (as per dmesg|grep ASUS).
The workaround is a line
for i in /sys/bus/usb/devices/*/power/control ; do echo on > $i ; done
in /etc/rc.local . Unfortunately this prevents powersaving of all USB ports/hubs.
What didn't work: I created /usr/lib/systemd/system/stopusb.service with
[Unit] Description=Power-on USB in prep for shutdown
[Service] Type=oneshot ExecStart=/bin/sh -c "for i in /sys/bus/usb/devices/*/power/control ; do echo on > $i ; done" ExecStop=/bin/sh -c "for i in /sys/bus/usb/devices/*/power/control ; do echo on > $i ; done" RemainAfterExit=yes
[Install] WantedBy=poweroff.target
but this seems to have no effect. Maybe the "poweroff" target does not really exist. I think someone more experienced with systemd could fix this.
HTH,

Forgot to say: the problem does not exist when "Wake on LAN" is disabled in the BIOS (but I need wake-on-LAN).

That did the trick. I was able to disable WOL and it no longer exhibits the problem, including being able to reinstall kexec-tools. A packet sniffer doesn't actually show up any WOL packets, though. It makes one wonder.
Thanks.
For the record, the motherboard is a Gigabyte Z87X-D3H.

Hi!

Maybe it helps to poweroff explicitly?
shutdown -hP now
I had the same problem on SUSE machines.
Cheers
