The only acpi-specific patches in mm(otm) are
acpi-add-checking-for-null-early-param.patch
acpi-avoid-dropping-rapid-hotkey-events-or-other-gpes-on-asus-eeepc.patch
mm-only-enforce-acpi-resource-conflict-checks.patch
so I'd say you've hit a linux-next regression there.
Random-possible-feel-it-in-my-water-guess: do you have CONFIG_FASTBOOT
set and if so, does unsetting it fix things?

I've just looked into my config file:
# CONFIG_FASTBOOT is not set

after 'quilt push linux-next.patch', I still saw the regression, and then
