dmesg

Right before the system go to suspend, the following line appears in
dmesg:

[drm:rv730_stop_dpm] *ERROR* Could not force DPM to low

After wakeup i see this in dmesg:

[drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed

Also i notice a degradation in performance in some games (e.g. in
Teeworlds before the suspend i have 60fps, after suspend - 30-40 fps).

Does this work better with a 3.14 kernel?

I've just built 3.14 RC6 and it's all the the same with it.

dmesg (Radeon HD 4550, 3.15.0)

I have the same problem with Radeon HD 4550 using kernel 3.14.5 or 3.15.0 or vanilla 3.15-rc1.
I have also noticed that `[drm:rv730_stop_dpm] *ERROR* Could not force DPM to low` appears only after some gaming/etc.

Bug description:
  Hello,
  On Ubuntu 14.04 LTS, when the computer starts (before the splash screen appears), I see this error in the console:

  [drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed

  I don't know what does exactly this bug, but I supposed that it's not
  normal.

  
  OS: Linux
  Type: amd64
  Distribution: Ubuntu 14.04 LTS
  GPU: ATI Mobility Radeon HD 4570
  → 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v]

  Kernel: 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014
  x86_64 x86_64 x86_64 GNU/Linux

  I use the free driver for Linux, ATI doesn't support this GPU with
  proprietary drivers today... but without this little bug, the free
  drivers are very good :)

  
  Message appears at [   17.026313]
  (See dmesg file)

  Thank you.
