Disconnecting a DisplayPort monitor while the system is suspended leads to a system hang (RX 6700XT)

Brief summary of the problem:

System hangs when resuming from suspend, when a monitor (DP/MST) is disconnected while the system was suspended. I run into this issue very frequently, because I often switch my display inputs when changing between my desktop PC and my work laptop.

When both of my displays (a Dell U2715H connected over displayport, and an old Samsung connected over HDMI) are connected, the entire system hangs while resuming if the Dell monitor is disconnected. In this state, the screens are black or don't wake up, SSH does not work, SysRq-REISUB sometimes works, and there's never any logs in the journal from after waking up the system (logs end with "suspend entry (deep)").

When only the DP display is connected to the GPU, the hang does not seem to happen, even though some warnings are still logged in dmesg.

When I connect the HDMI display to the Intel integrated graphics, the system hang does not immediately occur. After resuming, I can use the system as long as I don't try to do anything with the AMD GPU. There's this kernel warning in the logs in this situation:

The same warning appears when there's only one monitor connected, and that is disconnected while the system is suspended. But in that situation the system does not hang at least immediately.

I've reproduced the hang on kernel versions 6.7.3, 6.6.15, 6.1.77 and 5.15.94, so it's not a particularly new issue.

Hardware description:

• CPU: Intel i5 6600K
• GPU: RX 6700 XT (reference card)
• System Memory: 16GB
• Display(s): Dell U2715H, Samsung LS24E65UDW
• Type of Display Connection: Dell connected via DisplayPort, Samsung via HDMI

System information:

• Distro name and Version: Arch linux
• Kernel version: 6.7.3-arch1-1, 6.6.15-1-lts
• AMD official driver version: n/a

How to reproduce the issue:

Reproduce the hang

1. Connect one monitor (MST capable) with DisplayPort, another with HDMI
2. Boot the system
3. Close X11 / Wayland (e.g. systemctl stop sddm in my case)
   • Both displays show the console now
4. Suspend the system with systemctl suspend
5. Turn off the Displayport monitor connected to the AMD GPU
6. Wake the system up
7. Observe frozen system
   • HDMI monitor shows either a black or white screen or the console from before suspension. This behaviour differs between kernel versions
   • SSH does not work, there are no logs written to the journal...

Reproduce issue without immediate hang

1. Connect one monitor to AMD GPU with displayport, another to Intel iGPU with HDMI
2. Boot the system
3. Close X11 / Wayland (e.g. systemctl stop sddm in my case)
   • In my setup, the display connected to the AMD GPU is now black, while the Linux console is on the HDMI monitor
4. Suspend the system with systemctl suspend
5. Turn off the Displayport monitor connected to the AMD GPU
6. Wake the system up
7. Observe kernel warning in dmesg
8. Switch the Displayport display back on
9. Try to reset the GPU with cat /sys/kernel/debug/dri/0/amdgpu_gpu_recover, see the command hang

changed the description

marked this issue as related to #2314 (closed)

I believe this is a duplicate of #2314 (closed). Can you try the patch from there? https://gitlab.freedesktop.org/drm/amd/uploads/0e5a20ed8824816dc3029bff2e606748/0001-drm-amd-display-Skip-DSC-Determination-Policy-for-AS.patch

I tried the patch (with Arch's kernel 6.7.3); it had no effect. Still the same hang, and the same warnings in the logs. So this is likely something different.

I captured a bit more logs after the wakeup (this is with the Intel iGPU setup so that I can avoid the total system freeze), they show more logs about hung kernel tasks now.

journal-kernel-timeouts3.log

added 6000 dGPU Series DC hang/freeze labels

I just now found out (after about 5 years of owning this Dell monitor) that I can disable DP 1.2 and MST in the display settings. And with that my system no longer freezes when waking from suspend.

So this is definitely an issue with MST handling, but maybe not the same as #2314 (closed). But at least I now have a workaround (just don't use MST).

added MST label

OK, thanks for confirming that it's caused by MST handling and that it's not a duplicate of #2314 (closed).

Can you please reproduce again on 6.8-rc3, and if you can please capture logs with drm.debug=0x106 set?

Sure! The hang still reproduces, but the kernel warnings from fill_dc_mst_payload_table_from_drm seem to be gone.

Logs below. This is with plain 6.8-rc3 without any additional patches.

journal-kernel-6.8rc3-hang.log

journal-kernel-6.8rc3-timeout.log

(As before, -hang.log is with both displays attached to the AMD GPU --> system hangs on resume. -timeout.log is with the HDMI display connected to iGPU --> only AMD GPU hangs on resume.)

I'm also observing frequent hangs, broken displays output and other issues around suspending, and I believe detaching monitors before/after suspend plays a role. I haven't figured out a pattern yet tho.

• Kernel 6.7.6
• Thinkpad P16s AMD w/ 6850U
• Dell U3821DW (60Hz) monitor over USB-C in one place
• 2x iijama GB2560HSU (144Hz) monitors over HDMI via USB-C hub in another place

This is one of the occasions where it luckily didn't freeze on wakeup:

@luryus Please kindly apply below patches on top of 6.12 stable kernel and check behavior.

0001-drm-amd-display-Fix-incorrect-DSC-recompute-trigger.patch

0002-drm-amd-display-Skip-Invalid-Streams-from-DSC-Policy.patch

0003-drm-amd-display-Don-t-write-DP_MSTM_CTRL-after-LT.patch

Sorry, I completely missed this back in November.

I just now tested the issue again with both Linux 6.13.3 and 6.14rc3, and issue no longer happens on those! (These patches are included in 6.13 right?) So the issue is now fixed. Thank you!
