Build Identifier: 

If I try to shutdown, the shutdown sequence gets stuck at "reboot: Power down" but power-down doesn't actually happen.

Reproducible: Always

Steps to Reproduce:
1. Boot with kernel option "acpi_backlight=vendor". This is necessary or else the machine just gives a black screen (https://bugzilla.redhat.com/show_bug.cgi?id=1015881).
2. Login.
3. Try to shutdown from console with "sudo shutdown -h now".

Actual Results:  
Text shutdown sequence is shown, with final line "reboot: Power down", but no actual power-down.


Expected Results:  
Actual power-down.

Can you try passing the various reboot= options and see if one of them work?
They are:

warm, cold, bios, smp, acpi, efi, pci, force, kbd, triple

I would start with acpi, efi, and pci as those are the most common working options.

What laptop is this?

Seems similar to:

Hi Josh,

can you try kernel 3.12.6 which has the following commit:

commit 2ab0ff9b179aadf1f30f2dfa9db2b9404324e135
Author: Khalid Aziz <khalid.aziz>
Date:   Wed Nov 27 15:19:25 2013 -0700

    PCI: Disable Bus Master only on kexec reboot
    
    commit 4fc9bbf98fd66f879e628d8537ba7c240be2b58e upstream.


Some reports seem to indicate that Acer laptops are able to shutdown with that
patch.

You can find the kernel here:

Thanks and regards,
Michele

3.12.6 fixes the problem for me
