I have a Dell 15-7537 laptop install fedora 20 with kernel 3.14.8. But I can't power off my laptop using systemctl poweroff, Once I let systemctl power off my laptop, it will, but it actually do the reboot, I have to press power button on laptop or type halt in grub2, but it will cause the other reboot, after the second reboot, I could power off my laptop this time. But in the Windows 8.1, I don't need to do that, just click power off it would power off my laptop properly. I also have tried openrc in gentoo, it couldn't either. The kernel staff told me that kernel work well but it is the userspace's problem.
This is unlikely to be a systemd problem, since at some point systemd asks the kernel to actually do the deed. To test, can you do 'poweroff -f'? This talks directly to the kernel, bypassing the normal shutdown sequence.
I looked at the kernel bug and see that 'echo o > /proc/sysrq-trigger' works for you. To narrow it down, please still do the 'poweroff -f' test, and if it works, turn on systemd debugging with 'systemd-analyze set-log-level debug', and try to poweroff as usual, and after the reboot, post logs from previous boot: 'journalctl -b-1' output.

Yes, poweroff -f would poweroff the laptop. But systemctl poweroff will reboot, the log is too long, I paste it there http://paste.fedoraproject.org/119116/05709502/
Can you paste the relevant bits again? the fpaste is not available anymore.
I find my problem fix in new kernel, here is 3.15.8, when I report it the kernel is still 3.14. But I still have problem of poweroff after I reboot from windows, it is more likely the audio card problem in this laptop, the driver doesn't close the audio card in windows. Maybe the poweroff problem is caused by a windows driver.
OK, if the problem is gone with a newer kernel I figure we can close this bug.

I am very sorry, that problem doesn't been solved. Please re-open it.
