--- Comment #1 from xiaojian.du@amd.com ---
So you do one suspend cycle on your device?
I think CPU power status is reset after one suspend cycle.
Yes, it should be a function to restore CPU power register status and governor
status after s3/s4/s2idle.
For you case, i think add one more shell script will fix this problem, you
know, you are setting cpu enegy policy during booting, then your can add one
same action during suspend, any chance for this?
