Can't shutdown Acer Aspire S7 392

If I try to shutdown, the shutdown sequence gets stuck at "reboot: Power down" but power-down doesn't actually happen.
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).
3. Try to shutdown from console with "sudo shutdown -h now".
Text shutdown sequence is shown, with final line "reboot: Power down", but no actual power-down.
Can you try passing the various reboot= options and see if one of them work?
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:
can you try kernel 3.12.6 which has the following commit:

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
You can find the kernel here:

3.12.6 fixes the problem for me
