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

[Sven Joachim]

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.

If it is still unfixed, you may want to notify regressions maintainer,
and Linus.

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.

That bug is not public, unfortunately. :-(

Are there any news on this?  As of Linux 4.8.1, I keep reverting commit
274ad65c9d02, and I'd like not having to do that indefinitely.
