Comment # 1 on bug 1214073 from Takashi Iwai

That ACPI message doesn't appear when you reboot with the older 6.4.x kernel?
In anyway, please give the dmesg from the old kernel as well as hwinfo output.

Then, boot the new kernel with "nomodeset" boot option for disabling the
graphics.  If it's about nouveau, it should continue to boot.  Then give the
dmesg output from there, too.
