Subject: [REGRESSION] Laptop with Ryzen 4600H fails to resume video since 5.17.4 (works 5.17.3)
Date: Sat, 14 May 2022 16:41:19 +0200	[thread overview]
Message-ID: <2584945.lGaqSPkdTl@geek500.localdomain> (raw)

#regzbot introduced v5.17.3..v5.17.4

Hello
Since 5.17.4 my laptop doesn't resume from suspend anymore. At resume, 
symptoms are variable:
- either the laptop freezes;
- either the screen keeps blank;
- either the screen is OK but mouse is frozen;
- either display lags with several logs in dmesg:
[  228.275492] [drm] Fence fallback timer expired on ring gfx
[  228.395466] [drm:amdgpu_dm_atomic_commit_tail] *ERROR* Waiting for fences 
timed out!
[  228.779490] [drm] Fence fallback timer expired on ring gfx
[  229.283484] [drm] Fence fallback timer expired on ring sdma0
[  229.283485] [drm] Fence fallback timer expired on ring gfx
[  229.787487] [drm] Fence fallback timer expired on ring gfx
...

I've bisected the problem.

Please note this laptop has a strange behaviour on suspend:
The first suspend request always fails (this point has never been fixed and 
plagues us when trying to diagnose another regression on touchpad not resuming 
in the past). The screen goes blank and I can get it OK when pressing the 
power button, this seems to reset it. After that all suspend/resume works OK.

Since 5.17.4, it is not possible anymore to get the laptop working again after 
the first suspend failure.

HW : HP Pavilion / Ryzen 4600H with AMD graphics integrated + NVidia 1650Ti 
(turned off with ACPI call in order to get more battery, I'm not using NVidia 
driver).
