[Solved] Lenovo Yoga freezes on suspend

Blåklinten · 2020-11-16 15:57:19

Hi,

History

My Lenovo Yoga 530-14ARR has been running Manjaro for some time but I've had problems with the "suspend"-functionality.
The laptop worked fine for a couple of weeks but started to freeze on every fourth or fifth "suspend", which was very annoying.
I looked around but could not find anything obvious (tried booting with different command-line parameters and different configs but nothing fixed the issue.
I installed Arch, thinking it might solve the issue but on Arch the problem was instantly present on a fresh install.
I then tried installing Fedora and after a week or two the same thing happened there, it started to freeze when I tried to suspend the laptop.
I moved on to Linux Mint and a week into that I decided to try Arch, again (and this time ask you guys for help ).

The problem

On Arch the problem occurs instantly, i.e. when running `systemctl suspend` on a fresh install the system always freezes and I need to reboot.
I have tried following the solutions in this topic since it seems to be the same issue but it only resulted in my laptop not finding a screen and so I could not start X at all.
By reading, I have started to believe this is problem with the amdgpu driver, somehow and i am starting to loose hope.

What I am looking for

I need inspiration!
What might be the cause of this?
To me, it feels like a timing issue of sorts, i.e. the kernel and drivers are not getting along.
But how can it work (for some time, at least) on other distros then?
How can I debug this issue further?
I have tried reading/following these steps, without much success (I am not really sure in how to interpret the results).

Does anyone here have a suggestion on what I might do next?
It would really feel like a loss to leave this unsolved.
Thanks,
/L

Post info, hardware information and graphical setup.
Otherwise it's shooting in the dark.

More importantly, what have you done with your system thus far?

My system is a Lenovo Yoga 530-14ARR (AMD Ryzen 7 2700U with Radeon Vega Mobile Gfx).

I have no special graphical setup, mostly just the laptop screen but sometimes I also use an external HDMI-screen (do you mean something else but what screens I am using?).

At the moment I am running a vanilla Arch install with additions such as the GNOME-desktop environment (have also used Bspwm with the same result), Firefox, Git, GNUpg, OpenSSH among others. No display manager, I am manually starting X upon login.
I have tried adding the command line option "amd_iommu=off", this had no effect as far as I could tell.
Also tried adding amdgpu to MODULES in /etc/mkinitcpio.conf and created the configuration file `/etc/X11/xorg.conf.d/20-amdgpu.conf` as

Section "Device"
        Identifier "AMDGPU"
        Driver "amdgpu"
        Option "DRI" "3"
        Option "TearFree" "true"
EndSection

which resulted in X not starting, due to X not being able to any monitor.

I have tried downgrading the kernel to version 5.6.11 by means of the Arch Linux Archive (adding a server directive to /etc/pacman.conf and disabling integrity checks) but have not been able to succeed with this, I am getting package conflicts and I do not know how to resolve them.

As of now my system will freeze (i.e. keyboard backlight and power light still on but black screen, no SSH access and it is not possible to switch to another tty) if it is allowed to enter sleep/timeout/suspend.
Here are the output from `journalctl` regarding the last time the computer sat unused until it suspended;

Hope this information helps, if more is needed just let me know.

[Update]
I have done some more digging and debugging and found that it is probably a kernel bug.

It seems as if any kernel prior to 5.8 works but 5.8 and newer does not.

I have therefore, by using `git bisect`, found this commit that seems to be the root cause of my problem.
When manually reverting this commit on a kernel which prior to patching did not work, i.e. suspending made the computer freeze, the patched version works just fine.

I have started a conversation with the maintainer of the iommu subsystem to further investigate a possible fix to this issue.

are there any news on this? I've just set up my yoga with the latest ubuntu, but kernel 5.8 and 5.10 refuse to suspend.. only kernel 5.6 works

Blåklinten · 2021-01-11 12:07:13

No news yet. I am waiting for a response from the lead developer of the amd/IOMMU module and apparently he has been ill or otherwise not capable to work for some time. I have also tried CC:ing his temporary replacement but no response there either.

My fix to this, until a more permanent solution exists, is to manually compile my kernel after adding a patch that reverts the before-mentioned commit. This seems to work for me, at least at kernel 5.8.

Hi Blåklinten,

I've also responded on your post on https://forum.manjaro.org/t/suspend-wor … es/38897/2
but just in case someone stumbles on the same problem and finds this post, the bug has been fixed in the recently released kernel version 5.11.
At least, after trying that kernel version, my Lenovo Yoga 530-14ARR didn't freeze in the suspend sequence and restored the session after a key-press.

Kind regards!

Blåklinten · 2021-03-03 20:41:10

Thank you for the information rickiewars, I checked it out and kernel 5.11 works for me too!

I also noticed someone else had filed the exact same bug as me but had been more successful in reaching the maintainer. I have still not yet received any answer to my bug report but hey, at least the bug is now fixed.
