  Using the amd_pstate driver for a ryzen cpu.

  What i expected to happen: 
  Setting a low limit for scaling_max_freq and waking the computer from suspend. 
  The scaling_cur_freq should be below or equal this level.

  What happened instead: 
  The scaling_cur_freq goes above the allowed limit.
