Radeon: DPM suspend/hibernete error

Hello,

I'm testing linux-3.11-rc5 with my radeon graphics card HD 6470M. 
Finally hibernate and suspend mode started working without hangs. 
But now I see this error message in dmesg before notebook it 
hibernated or suspended:

[drm:rv770_stop_dpm] *ERROR* Could not force DPM to low.

Is this ERROR message big problem? Can you look at it?
Note that suspend/resume and hibernation working fine.

Thank you very much for DPM & UVD support!

There is an open bug:
https://bugs.freedesktop.org/show_bug.cgi?id=67790
you can follow along there.

I haven't had a chance to investigate it much yet, but I think it's probably harmless.
