Public bug reported:

This happens on a Dell Latitude E6540 (4th gen core i7 CPU).

Steps to reproduce:

1) normally boot the computer and make sure  everything works as expected (i use the ondemand governor)
2) suspend
3) make the computer is unplugged and resume

Expected behavior: cpu should work normally
Actual behavior: cpu always stays at minimum frequency (in my case 800 MHz)

If i resume from suspend while plugged to the AC charger, everything
works as expected.
