Description Johannes Hirte 2013-08-05 13:16:21 UTC 
On suspend dmesg shows the following error message:

[  236.137036] PM: Syncing filesystems ... done.
[  236.673588] Freezing user space processes ... (elapsed 0.007 seconds) done.

I've not seen any problems, suspend and resume worked correct so far.

I see same error message in dmesg with kernel 3.11-rc5 when my notebook is suspending or hibernating. But suspend and hibernate working fine. I have Radeon HD 6470M card.
[drm:rv770_stop_dpm] *ERROR* Could not force DPM to low.

This is printed with my Barts GPU as well, which seems to indicate that the function is slightly misnamed.
Comment 3 xorgx3 2014-12-28 10:26:16 UTC 
Bug still persist in  3.18.1 kernel. And it's very annoying, because in my laptop(Radeon HD5400) I cannot return from suspend/hibernate because of this bug, and I need to restart computer...
Comment 4 Alex Deucher 2015-01-02 22:45:43 UTC 
The code is shared across several generations of hardware.  As long as suspend and resume works ok, it can be ignored.
