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.
Bug https://bugzilla.redhat.com/show_bug.cgi?id=1269009
Cheers,
Jérôme

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.
Cheers,
Sven

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