I'm currently running on latest Manjaro XFCE with the 4.15 kernel just released, and I found that the system would crash when trying to wake up after the screen went blank. The system is an AMD Laptop (ASUS ROG STRIX GL702ZC), and the problem is 100% reproducible with the following steps: - Lock the screen, leave the screen blank for at least 3-5 minutes. - Try wake the screen up, like moving the mouse cursor. At first I did not find the cause, but after looking into the journalctl I was able to find something that appears to be a kernel panic. It existed since the beginning, with the 4.14 kernel, and remained unsolved even after upgrading to 4.15 kernel.

The bug report here, which was closed last December, resembled my current issue: https://lists.freedesktop.org/archives/amd-gfx/2017-November/016236.html I've thought about the possibility of it being DC-related as I saw similar bug reports, but I was wrong, as at one time I was able to reproduce it even after passing amdgpu.dc=0 during boot. The modules don't seem to be related, as it happened on fresh installs, where I left the screen blank (before I actually adjusted power management options) as I let it download and install packages I wanted in the background. Additionally, I'm able to find some additional errors prior to the crash, which might have happened when the screen went blank. It could be done by simply locking the screen and leave it as is. (NOTE: When I locked the screen and then immediately move the mouse cursor to wake it up, the crash would not occur. It would only occur if the screen went blank for at least 3-5 minutes.)

For now, I could only prevent the panic from happening by not allowing power saving functions to happen, especially anything that would turn off the screen. I'm also not allowed to lock the screen it would also blank the screen, and the GTK+ greeter could blank the screen in its own way. However, it's not feasible for running the system on battery for an extended period without any power saving feature, given the high total TDP the laptop has, and leaving the system unlocked is a bad idea in terms of security and privacy. By the way, given there were a few similar closed bug reports in the past, I believe the problem might be a regression.

The rest of your report mostly points towards a DC specific issue. If you can still reproduce an issue without DC, it would be best to file a separate report about that.
l too have same problem.
Sorry, i'm forget write. I too have same problem, but on Desktop*.
Just now I tried reproducing it without dc (passing amdgpu.dc=0) but somehow I was not able to... the system was able to successfully get back to the lock screen after letting it blank after an extended period. As for that time I did manage to reproduce... maybe I passed the parameter wrong or for some other reasons, but for now, will keep the issue DC-specific as it's always reproducible with DC enabled (Arch/Manjaro enables DC by default including pre-Vega).
Can you attach a full dmesg log with amdgpu.dc_log=1 and drm.debug=6 passed as kernel options?
Created attachment 137308 [details] dmesg output with amdgpu.dc_log=1 and drm.debug=6, right after login. I'm not sure to what extent is a "full" dmesg. Attached is the dmesg I exported right after startup, with the above parameters passed.
And I just crashed my system the same usual way. With those parameters set there are some additional outputs besides the usual ones.

Created attachment 137327 [details] [review] Patch 2 Return success when enabling interrupt Goofed up my original patch 2. This should work.

Never mind, just figured out how to properly adjust the patch file to match the kernel source I got so the patch file gets to be properly applied... it seems the rest of the patches went through without complaints and the kernel's now building... However, I still need to be check if this one-line change in the patch will lead to any side effects during build or during runtime...
Just installed and booted the new kernel. It seems to have fixed the issue at least to the extent that it would not totally crash the system like it used to. However, I still see these in journalctl.

Thanks for fixing the patch conflict. I based them on https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next but should have based them on the 4.15 kernel. Thanks as well for testing. The patches don't fix the root cause of the issue but make sure you don't crash in this case. Catching the root cause is a bit more difficult and would require more debugging. I haven't seen the "Failed to get VBLANK" on platforms available to me but will keep an eye out for it.
I applied the patch to 4.15.3 on archlinux and have tested with xset dpms force {standby,suspend} with success.
Created attachment 137383 [details] stacktrace even with patches I just got another freeze despite using the patches. I'm not sure if this is the same bug since it mentions slub.c but I see amdgpu/drm stuff in the trace. After this trace the journal was flooded with items like "amdgpu_dm_irq_schedule_work FAILED src 4" (it alternates between 2 and 4)
I've been using this patchset on linux 4.15.3 and 4.14.4 and haven't had a problem since.
Another problem: When I woke up the screen, sometimes the system would have intermittent soft lockups that made the system kind of unusable... This is after I included the patch to the latest 4.15 kernel, 4.15.5 (4.15.5-1-MANJARO) In journalctl I find the following phenomenon. During its sleep the error "failed to get VBLANK" is being written every 20s. Feb 27 11:57:29 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Failed to get VBLANK!

Feb 27 11:59:49 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Failed to get VBLANK! After I woke the screen up and I get the intermittent soft lockup issue, the error "dc_stream_state is NULL for crtc '1'" is written multiple times from either dm_vblank_get_counter or dm_crtc_get_scanoutpos every 8 or 18 seconds, which seemed to correspond to the lockup interval. I did not test the issue further as the system was almost unusable due to the lockup and I had to reboot.

It just happens from time to time.
It seems some of the patches (1, 2, and 4) have entered the 4.16 kernel, from what I can tell when building the kernel for Manjaro, where these three patches got rejected, and the exact code changes were found in the original kernel code files. However, after some testing I found out that the patch 3 (which is not included) is still needed for 4.16 to fix this the problem, as I can still crash the system without it.
EDIT: It seems I'm experiencing some intermittent screen flicker with current 4.16 kernel (on the same system, with only Patch 3 applied as it's the only patch needed for 4.16), although it doesn't really affect normal system usage. I'm not sure if this flicker is related to this problem, but I'm putting it up here as it's still a continuation of my watching this issue's condition.
My stability has been fine since I last commented. I'm now on 4.15.10+these patches. However, my monitors won't turn off: When the screen turns off it'll come right back on after a second. Just now I also had my second panic just like in #19, sadly (really bad time to have that happen, too) :(

Do you have TearFree on? https://bugs.freedesktop.org/show_bug.cgi?id=105530
Also propably related: https://bugs.freedesktop.org/show_bug.cgi?id=101580

And I'm only getting the flicker on 4.16 kernel, on 4.15 it is and has always been fine.
Just updated to the 4.17-rc0 kernel and it seems the problem has been mostly fixed there. The patches are no longer needed (already in there) and trying to reproduce the issue only resulted in a couple of "Failed to get VBLANK!" errors that aren't fatal. I'm not certain about the flickering issue I mentioned earlier... It looked like one but might actually be some kind of sudden color palette distortion. The problem only appeared since 4.16. I don't recall having the issue in 4.15. I can partially reproduce it in the Firefox new tab page, by quickly hovering over the links on the "Top Sites" and "Highlights". The whole screen would turn a bit darker in color for a very short instant then returns to normal. It happens randomly and it doesn't seem to produce any errors in the log. Not a major issue, just it can be annoying sometimes.
EDIT: Maybe not really fixed in 4.17 (regression again?!)... just now after the screen went blank, I got another panic and had to reboot... :-( When the panic occurred, it spawned two errors.

EDIT 2: I couldn't reproduce the issue on 4.17 this time even after 2 wakeups. However, the issue I encountered was similar (system apparently froze when trying to wake up the screen). After looking into it, I found that along with the errors that showed up like that in Comment 16 (which did not crash the system), there was an additional "kernel BUG" related to dm_update_crtcs_state which was called by amdgpu_dm_atomic_check, but the log appeared to have been cut (the log entries between the two errors were apparently unrelated to the error so I did not include them, and the new error began with a "--[ cut here ]--"). This additional error (not 100% reproducible) might be what actually crashed the system that time.

So it seems there definitely is a regression on 4.17 on this issue (the patches are not required as the lines were already there in 4.17). This time it isn't a kernel panic, but an "invalid opcode" error caused by dm_update_crtcs_state that was called by amdgpu_dm_atomic_check. The issue is not 100% reproducible, but still means going to standby with an AMD GPU and DC is still dangerous and may result in losses of unsaved work.
In my case the problem was not having xorg-x11-drv-amdgpu installed (how embarrassing) which made xorg use xorg-x11-drv-ati. Yes, really. I assumed Fedora 28 beta installed it along with all the other drives and didn't realize until comparing the X logs on a box which didn't have a problem with one that did. I did file the Fedora bug kindly asking xorg-x11-drv-amdgpu to be installed as a default. Simply installing xorg-x11-drv-amdgpu solved this error and amdgpu kernel crash: [12743.692030] kernel BUG at drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4708! I realize the immensity of my stupidity not realizing xorg-x11-drv-amdgpu will make you laugh but it's not like the kernel panic message warned me.
While it's good to hear that xf86-video-amdgpu doesn't trigger it, the kernel BUG is still a kernel driver bug.
I believe I've been seeing the same bug as of late.

I have a 144Hz FreeSync-capable monitor, and can easily reproduce the error with this command (where 143.86 is the xrandr-advertised maximum frequency): xrandr --output DisplayPort-0 --mode 2560x1440 --rate 143.86 --set "scaling mode" "Full aspect" Interestingly xrandr reports 59.95*+ as the current frequency, but my monitor says 144Hz. I tried firing up Grey Goo under Wine and that game reports my monitor running at 144Hz also. If I just run: xrandr --output DisplayPort-0 --mode 2560x1440 --rate 143.86 then xrandr correctly reports 143.86* indicating that that frequency is now selected. I can also run the following: xrandr --output DisplayPort-0 --mode 2560x1440 --set "scaling mode" "Full aspect" But if I combine these options as per the first command above, I get GUI crash. The symptoms are simiar. In my case the screen is still on (not blank) but completely frozen. I was able to SSH in to get the above trace from the dmesg command. The machine cannot successfully shutdown or reboot and I need to physically hard reset the box at this point. As others have said, this is definitely a regression. This didn't happen in older kernels.
The kernel BUG should be fixed since 4.17 by this commit commit 20d4ac659c76034586a3ab79489b0940631a65de Author: Leo (Sunpeng) Li <sunpeng.li@amd.com> Date: Tue May 29 09:51:51 2018 -0400 drm/amd/display: Fix BUG_ON during CRTC atomic check update For cases where the CRTC is inactive (DPMS off), where a modeset is not required, yet the CRTC is still in the atomic state, we should not attempt to update anything on it. Previously, we were relying on the modereset_required() helper to check the above condition. However, the function returns false immediately if a modeset is not required, ignoring the CRTC's enable/active state flags. The correct way to filter is by looking at these flags instead.

Attempted to lock the screen and leave it blank for a while to see what happens, and it seems for the first time there are still errors related to VBLANK, but they appear minor as the system woke up just fine. I tried letting the screen blank twice this time, and the errors did not show up the second time. Only during first time did the errors appear, though this is probably not enough to prove much. But still, I don't see that kernel bug this time so that must have been fixed. I'm yet to assess whether the bug can no longer be reproduced as I've been avoiding having to leave the screen blank, as back then this bug has caused losses of unsaved work and other problems due to the crash.
