Wake up from suspend problem

English Install/Boot/Login
1

Hi,
My old mobo was failing and decided to build a new budgeted desktop.
This one has a new case, mobo, cpu and ram. I re used my existing GPU, PSU, two SSD and HHD. The new mobo is an ASUS B650E-F and the cpu is AMD Ryzen 5 7600X.
The two SSD contains tumbleweed and the HDD is a storage.
I was able to boot the SSD with tumbleweed with no problem but my problem now is it doesn’t wake up from suspend. The monitor is black, keyboard and mouse is not detected also.
If you need further info. I will happily provide. Lastly it seems I don’t see any output when I tried to rebuild the initramfs with “dracut -f --regenerate-all” command as root.

Thanks in advance.

Too late for an edit. I just want to re-phrase one word from my first post. This is a low budget desktop I used my old age pension to build this one :blush:

@conram likely need to look at the logs. If you have to power cycle, just use journalctl -b -1 -r the -r to go in reverse, latest to oldest. Maybe drm related, could try adding amdgpu.dc=0 to see if that makes a difference;

update-bootloader --add-option amdgpu.dc=0
update-bootloader
systemctl reboot

Hi, @malcolmlewis I added amdgpu.dc=0 in the kernel parameters and rebooted still no go. When I go to suspend it seems it is only the monitor and periphrals stops. All the fans are still rotating including the atx fan.

I booted to the other SSD with an old tumbleweed (my backup) If I add amdgpu.dc=0 to the kernel parameters and reboot suspend work the mobo came to halt including the atx fans but don’t wake up from suspend.

dracut still works in the old tumbleweed and shows output. In the newer tumbleweed with the latest dup there is no output for dracut. Is this newer tumbleweed corrupted

@conram then I would persue freedesktop drm amd bugs (one of the reasons I’ve steered clear of AMD :frowning_face: )

When I had the RX550, this was (and still open AFAIK) made me throw it away;

Some other thoughts, do you have swap? I use zram here. Also look at fwupdmgr security may point out something in the list, there could also be firmware updates, so as root user run fwupdmgr get-updates to see…

I also only use suspend on a couple of Dell’s one is a Micro 3080 with Windows 11 Pro and Tumbleweed (grub-bls) Intel 630 GPU, the other is a OptiPlex XE3 with Leap 16.0 Nvidia Quadro T400 (Intel 630 is Prime Render Offload) and I just press the keyboard (Fn+Sleep) after that any key press brings the systems back to life… Oh and I’m on GNOME/Wayland (of course…)

Another thing to check is that BIOS revision is the latest available for the motherboard.

If that does not help can try instead amdgpu.dc=1, I am using that parameter on the i5-6600k here.

This is unfortunate to hear :disappointed:. The RX550 here does work fine with hibernate and suspend on (i5-6699k). Also a recent problem with DRM messages flooding the logs has been corrected. :< Making sure you're not a bot!

More thoughts:
Please try to disable bluetoothat BIOS level firstly, if not possible then elsewhere (OS level)and test suspend again.

What is the output of:

cat /sys/power/mem_sleep

I believe that s2idle [deep]is what you want to see.

@malcolmlewis I did the fwupdmgr, there were some update, still no go.
Yes I have swap a big one. My first choice was to go for Intel but budget wise here is kinda short so I went for the AMD it’s a bit affordable, probably this is one of the downside, you get what you paid for. I was asking also regarding the dracut command, I tried dracut with --option “verbose” and it trows output so that could be the norm when using it.
@panorain I tried amdgpu.dc=0 and didn’t work. s2idle is “deep”.
Could be my last resort is to update the bios to the latest. I didn’t flash the bios so it is still using the factory default with a release date sometime in July 2025. I didn’t update it to see if it’s gonna work after my assembly of this rig if it will work right away.
Thanks for responding, If anyone has an idea feel free to respond, any response is deeply appreciated, thanks in advance.

@conram so you can remove with the --del-option amdgpu.dc=0.

So swap could be the issue… How much system RAM and how big is your swap?

11

Hi, Like I said it’s a big one :grinning:
It’s 30 GB. It’s the original configuration from my SSD and HDD with tumbleweed that I relocated to this new rig. It is big because when my GPU before was not good I set it to have the large swap for rendering in blender because I was using CPU. The RAM of this new one is 32GB.

I would like to add that this tumbleweed is running fine since 2015 with just keep on doing the zypper dup :heart_eyes:

13

@conram Then as a test, I would edit /etc/fstab and comment out the swap line, then install zram-generator and use the following configuration;

Filename: /etc/systemd/zram-generator.conf

[zram0]
zram-size = ram * .5
compression-algorithm = zstd
max-comp-streams = 4
swap-priority = 100
fs-type = swap

The comp-streams is set to utilize a third of the cpu cores (4)

Start and enable the service with systemctl enable --now systemd-zram-setup@zram0.service (Ignore the warning that spits out…)

Reboot and see if that makes a difference.

I would recommend updating to the latest BIOS as well…

Will do. To be honest I am a bit scared flashing the bios right now, been a while since I did it. Any suggestion of safely doing it I am using an ASUS mobo. Actually I already downloaded the latest bios firmware before assembling this rig. When searching of flashing the bios it’s all for windows I see. In old days there was a way doing it in linux, I did it once and it was successful but haven’t hear about it now. If memory serves, old_cpu one of the moderator here had posted an article of how to do it in the old forum.

@conram Is this the model motherboard you have?

@conram Not sure, my HP’s I can do from Linux or the BIOS, the Dell’s use fwupd…

17

@panorain That’s the one

18

Yes I did it too in HP

Driver and Tools section states the following:

Version 3287

14.65 MB 2025/10/27

SHA-256 :9EC12FE77EDB20ADA34F63A14D4389B5E3666E8FF95EBC7032B661B70D6BCCBB

"Updated AGESA to ComboAM5 PI 1.2.0.3g.

Before running the USB BIOS Flashback tool, please rename the BIOS file (`SB650EF.CAP`) using BIOSRenamer."

There may be an option to update the BIOS within the BIOS settings page itself (most likely).

In the above codebox it says:
Please rename the BIOS file (SB650EF.CAP) using BIOSRenamer.

So must find out what the BIOSRenamer tool is. Then you can change the name of your harvested BIOS file name to SB650EF.CAP.

Check out this information (with video). https://www.asus.com/us/support/faq/1038568/

Note: Looks like a very recent BIOS revision.

Is this the error you want to ignore?

/etc/systemd # systemctl enable --now systemd-zram-setup@zram0.service
Failed to enable unit: Unit systemd-zram-setup@zram0.service does not exist
