without the acpi_osi='!Windows 2012' parameter?
I have been using the 3.13 kernel since i believe rc3 was out and i have not
had any issues
though i have been using the acpi_osi='!Windows 2012' parameter in grub

on a side note on my amd desktop with the 3.12.9 kernel if i set the cpu
governor to userspace and select a frequency when i wake from suspend the
frequency changes to 100%
should be reproducible on intel system that are not using the new intel_pstate
cpu frequency manager
This is the script i use to manage the governor
