Hi,
I also experience this problem with my laptop at resume from sleep.
About log messages, there does not seem to be a message when entering
sleep. When resuming from sleep, I can briefly see this message printed
on the screen:
kernel: [drm:rv730_stop_dpm [radeon]] *ERROR* Could not force DPM t
I forgot to mention the OS I'm using:
ArchLinux x86-64
Linux 4.0 from testing repo (also happens with the kernel from core repo)
mesa 10.5.4 from stock core repo
xf86-video-ati 1:7.5 from stock core repo
No patch, no personal kernel boot options, basically zero config.

Ardien at https://bugzilla.kernel.org/show_bug.cgi?id=71891 they state
"...found in the kernel source file drivers/gpu/drm/radeon/rv770.c.
Despite the name this function is used for RV710, RV730 (yours) and
RV770.". So my uneducated guess is that the patch does apply to you.

I can duplicate this problem with CentOS 7.1.
When I run kernel 3.10.0-229.1.2.el7.centos.plus I don't see (or at
least notice) the performance issue after resuming from suspend, however
I do receive the same errors. Additionally X will randomly hang (maybe
5% of the time) when I resume, I suspec
I just realized that another performance issue I had is actually caused
by this bug. This occurs with kernel 3.10.0-229.1.2.el7.centos.plus
(and probably all kernels). After I suspend/resume scrolling in gnome-
terminal is very slow. For example if I 'cat /var/log/messages' then
scrolling in gno
I tried with option radeon.dpm=0 and yes the message disappears at
resume from sleep.
But on my machine I never noticed graphics slowdown (at least with
vlank_mode=0 glxgears). I'm not a consumer of fancy graphics or games.
However what I noticed without that option was buggy scrolling in
Firefox
On my machine this only visible thing this radeon.dpm=0 does is to
silent the error message at resume from sleep. I see no graphic perf
increase (at least with glxgears) and still scrolling issue for the app
that had it (assuming it is actually related to graphics).

Does this patch help? You will still get the error messages, but
everything else should work.

Yes, the new patch behaves exactly as you describe: I don't see any
performance degradation after suspend/resume, although error messages
are still present.

This patch will quiet the errors unless you enable driver debugging.
