Hibernation broken since commit 274ad65c9d02 ("drm/radeon: hard reset r600 and newer GPU when hibernating.")

Recently I got myself a new laptop with the following integrated GPU:

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R3 Graphics] (rev 40)

I found that hibernation is broken in Linux 4.7+ (it works in Linux 4.6) and bisected it to commit 274ad65c9d02 ("drm/radeon: hard reset r600 and newer GPU when hibernating.").

This has already been reported three months ago, but for a much older GPU, see the thread starting at
https://lists.freedesktop.org/archives/dri-devel/2016-June/110050.html.
The symptoms are exactly the same as described by Boris Petkov in that
thread: after "systemctl hibernate" the screen goes blank, but the machine remains powered on and needs to be power-cycled.

Any suggestions would be welcome.

Cheers,
Sven

I guess we can invert the logic and only do it for the GPU for which it fix hibernation.

No that's the issue, i don't have hw anymore but according to bug it is AMD FirePro M5170 and M6170 which would make them amdgpu afaict but i remember the hw was using radeon so i am not sure how to figure out what GPU it was really.
