--- Comment #10 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) --- Please post a full dmesg log and Xorg log from your 4.18 kernel.
If your setup differs from the original poster then it would likely help if you noted your distro/desktop environment as well.

--- Comment #14 from Eduard (wirch.eduard@gmail.com) --- Attached dmesg output right after boot (boot log 4.18) and the additional failure lines after display woke up from power save (fail log 4.18). As well as Xorg log (Xorg 4.18).
The problem behavior is the same as with 4.15. After waking up the display from power save, the system freezes every 10s for a couple of seconds.
https://bugzilla.kernel.org/show_bug.cgi?id=199139
--- Comment #15 from Eduard (wirch.eduard@gmail.com) --- @Nicholas: you got some insights from the logs?
https://bugzilla.kernel.org/show_bug.cgi?id=199139
--- Comment #16 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) --- The logs are sufficient in case to understand what issue you're experiencing.
However, I'm surprised that this is occurring with xf86-video-amdgpu. Another user with a similar setup was reporting this problem only occurring with the modesetting driver - but they were using GNOME instead of xfce.

--- Comment #17 from juliolokooo@gmail.com --- It can be reproduced on 4.19.0-rc6 too, same dmesg and Xorg output as with 4.18. I tested on XFCE with xf86-video-amdgpu and modesetting, this bug happens with both.
https://bugzilla.kernel.org/show_bug.cgi?id=199139
--- Comment #18 from Eduard (wirch.eduard@gmail.com) --- Even after updating to 4.19 release did not solve the problem.
I was able to work around it by disabling monitor power management in Xorg settings:
Section "Monitor" Identifier "Monitor0" Option "DPMS" "false" EndSection
I sill get this error:
kernel: [drm:dce110_vblank_set [amdgpu]] *ERROR* Failed to get VBLANK!
But it does not repeat every 10s any more, and also my system does not freeze. So I can finally upgrade from 4.14.

--- Comment #19 from Eduard (wirch.eduard@gmail.com) --- I figured out it is not true. After a longer period of turned off screen (lightDM automatically turns it off if you lock the station), the hangs appeared again. So I'm back again on 4.14. :(

--- Comment #20 from Eduard (wirch.eduard@gmail.com) --- @Nicholas: If you understand the root cause, can you suggest a work around for this problem?

--- Comment #21 from Eduard (wirch.eduard@gmail.com) --- I was able to work around the problem after a hint by Michel Dänzer by disabling new amdgpu display code: https://bugs.freedesktop.org/show_bug.cgi?id=109001#c11

--- Comment #22 from mistarzy@gmail.com --- I got rid of the issue by clean installation of Xubuntu 18.04.1 with 4.15. Same kernel on old installation (xubuntu being upgraded over the years from 15.04 to 18.04.1) that I mentioned on 2018-09-14 still has issues. I was trying to find source of the issue but I do not believe that was kernel related. Since on fresh installation everything works fine. Also when switched to mainline https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20/ no issues found. My skills are limited but would guess is how system is handling amdgpu driver. If you would like me to test something I have both installations available - with and without drm issue.

--- Comment #23 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) --- Does this still occur on kernels for 4.21 and higher?
It isn't directly related to power management, but there are many of these classes of edge cases with atomic commit flow that get fixed with the following patches:
https://patchwork.freedesktop.org/patch/263411/ https://patchwork.freedesktop.org/series/53324/
So I would be interested in knowing whether this is a separate issue.
