Good morning, maeschba

Does `amd_iommu=off` in kernel parameters mitigate this issue? It should let the device sleep and come back from sleep, it might also help with the fan always on
We will look into the ACPI tables issue, as fixing it might make us not depend on `amd_iommu=off` as it disables IOMMU as a whole

If you do need IOMMU for your system (eg, PCIe passthrough for VMs), you'll have to not use the `amd_iommu` kernel parameter

Regards,

Good morning, Samanta

No, unfortunately it does not. First try, it went just back to the login screen. On second attempt, the system went black and I had to power down the laptop with the power key. There is a bigger problem than just the sleep behavior.

The BIOS is causing kernel memory corruption:

I should probably stay in the console (tty) and avoid touching the touchpad until the BIOS is fixed. In the first place, I was in console mode when I realized that the fan was spinning while the temperature of the CPU is under 30°C. Judging form the translation error in the BIOS (Performmance [sic] mode) and the small number of options, the BIOS seems to be the culprit.

• HTIX5288:00 36B6:C001 Touchpad: kernel bug

• System freezes often start with touchpad interaction

• Memory corruption follows touchpad errors

This laptop needs a serious BIOS/ACPI fix.

Framework ships the same CPU family with working Linux support. What's your timeline for fixing the ACPI tables?

Hello,
This is the first time that we have been notified that the touchpad causes freezes in this laptop.
As Arch is a bleeding edge distro, it might be a kernel issue, if you could try using an LTSC kernel or a Live CD with another kernel that isn't 6.18 to see if the touchpad errors still occur

For what is worth, this laptop needs 0x610 for amdgpu.dcdebugmask, as that disables all PSR technology which we know has caused issues with AMD laptops, so you can also try that for the freezes

Regardless anything, we are still investigating the ACPI errors mentioned here

Regards,

I tested suspend also on Slimbook OS r13 live USB (kernel 6.14.0-1019-oem with your default parameters). Suspend fails:

• Screen goes black

• Fans continue spinning

• Keyboard backlight stays and toggles

• System does not enter S3/suspend

• Cannot wake - requires hard power off.

Please provide a timeline for a BIOS fix. In its current state, the product is not fit for purpose.

Good morning,

Default kernel parameters of the live CD of Slimbook OS do not provide `amd_iommu=off`, only `amdgpu.dcdebugmask=0x610`
You would need to edit the entry and add the amd_iommu parameter

Regards,

The fact that amd_iommu=off is needed means your ACPI tables are broken. This is a firmware bug, not a configuration issue.

Questions:

When will you release a BIOS update that fixes the ACPI errors so these workarounds are not needed?

Other customers are reporting similar issues. What is your plan to address this systematically?

I've documented kernel memory corruption (BUG: Bad page map), failed suspend, broken power detection (_PSR), and missing GPU ACPI methods (VGA.AFN4). These are firmware defects. Kernel parameters are workarounds, not solutions.

By disabling the touchpad, not using any kind of suspend, and ignoring the fan running constantly, I can work more or less without system freezes. As far as I understand, the KDE Slimbook VII's current issues are:

• Power source detection broken (_PSR method fails)

• GPU ACPI methods missing (VGA.AFN4 unresolved)

• Fan control not exposed (EC-controlled only, no hwmon fan sensors, no ACPI binding)

• Touchpad errors (I2C relies on ACPI) - kernel bug: clickpad advertising right button

• Memory corruption (BUG: Bad page map, Fixing recursive fault) - historically observed, but less with workarounds* applied

• System freezes (cascade from above issues)

• S3 suspend broken (screen blacks out, fans spin, keyboard backlit, doesn't actually suspend)

* using Arch's linux-lts kernel most of the time, with kernel parameters amd_iommu=off and amdgpu.dcdebugmask=0x610, as well as kernel module i2c_hid_acpi blacklisted

Hello all 

I have the exact same model (Silver Excalibur with AMD 7840HS & 780M) with same symptoms and problems..

Samanta

"For what is worth, this laptop needs 0x610 for amdgpu.dcdebugmask, as that disables all PSR technology which we know has caused issues with AMD laptops, so you can also try that for the freezes"

when you disable PSR technology, battery drain goes sky high.I can't work more than 2 hours (at best) without plugging...

Please FIX it....

Regards

Theodore

Good afternoon @theodore,
Your model is not the same as KDE VII, your model uses an older CPU and GPU and is the KDE V model

I recommend contacting support, as this is not the same issue or at least not from the same model

Our support team will help you

Hello, 

I have exactly the same issue.  My laptop is a SLIMBOOK EVO with arch-linux. This is what happened: 

• [01/01/2026] System update. 

• [29/01/2026] My computer stopped suspending on lid close. No updates between 01/01 and 29/01 

• [30/01/2026] System update. My computer did not suspend on lid close either

• [30/01/2026] Inspection of the problem: 
     1. My computer does not suspend at all. Even if I force it: 
  

        $  systemctl suspend

     2. It does not hibernate either. 
     3. Under suspension, the service system-logind says: 
  

          Jan 31 09:29:15 cubo systemd-logind[613]: Lid closed.
          Jan 31 09:29:15 cubo systemd-logind[613]: Suspending...
          Jan 31 09:29:17 cubo systemd-logind[613]: Operation 'suspend' finished.

         It "finishes"  with no reason after 2 seconds. Every 30 seconds, the machine tries to suspend again with no success. 
  dmesg says:

     4. I went to the BIOS, but it is 100% non-responsive, neither via keyboard not via mouse. I get to the screen (it takes a long time) but there is nothing I can do on it.  GRUB is reesponsive but it takes a second per keystroke at least.

Good morning all 

@Samanta I forgot to write that I was referring to the BIOS version NOT the laptop model. I know it's different laptop. 

@maeschba I don't know if it's possible for you but because of all these troubles with sudden reboots or sudden freezes I re-formated my laptop and installed CachyOS with Hyprland. Before that, I was always using KDE with either Arch or Fedora and some time openSuSE Tumbleweed.

After switching to Hyprland and using "amd_iommu=off dmgpu.dcdebugmask=0x610" in grub file, I HAVEN'T ANY CRASH and/or REBOOT.

I don't know if it's relevant or not, luck or not, but these factors permitted me to use laptop without the problems I mentioned. I also use extensively QEMU/KVM machines also WITHOUT problems.

Of course I know it might not be possible for others to do what I did, but I thought to write it down just in case :)

Theodore

Hi Theodore

With Hyprland, you're probably using mostly keyboard. I had similar success with Sway (no freezes). My crashes involved Firefox + touchpad interaction. After disabling the touchpad in KDE (mouse only), I had just one freeze. Now I've blacklisted i2c_hid_acpi entirely - even accidental touches should be safe. Thanks for confirming CachyOS/Hyprland works. Hoping for a BIOS fix soon - workarounds on a "Linux laptop" defeat the purpose. What browser do you use?

Regards, Michael

Hello Michael

To be honest, I "hate" using touchpad. I prefer and try to use mouse :)

Yes, Hyprland is MOSTLY keyboard but mouse actually helps. I was using Vivaldi, but lately tried Floorp first but settled with Zen browser. Both are Firefox derivatives. 

Theodore

Hi everybody, 

if I let the battery drain completely until the computer shuts down, then, 

1. BIOS works as expected, 

2. Suspend works. 
   

However, the kernel error persists, and today it was working properly for some hours until it broke again. 

Paula

Hello Paula,

Is this for the KDE Slimbook VII (Ryzen AI 300)? Draining the battery resets the EC (Embedded Controller). What specifically "broke again" and what do you mean be BIOS works as expected? 

If you run dmesg on your system, does it also show an error message like this?

Jan 11 22:03:39 archlinux kernel: ACPI Error: Aborting method \_SB.ADP1._PSR due to previous error (AE_NOT_FOUND) (20250807/psparse-529)

Good morning @Paula,
Since I see that your Arch Linux installation was installed by yourself, I ask you if you installed our meta-packages for kernel parameters (specifically, the acpi no wakeup one! to make it able to suspend)
The EC from your EVO might send sporadic wakeup signals that might prevent the laptop sleep. As the wakeup signals are random,  that is why you probably got to suspend your laptop correctly last time you mentioned it

As for the "non-responsive" BIOS settings, to rule out any misunderstandings, Bluetooth and 2.4 Ghz dongles will not work on BIOS,  so you must use either USB or the built-in devices (not saying you used Bluetooth or 2.4Ghz, but do not want to assume things)

As for the ACPI errors of your EVO, we understand it is a BIOS error, and until we fix it, the kernel parameter mitigates it. 

The EVO BIOS and EC and the EXCALIBUR/KDE VII uses both different BIOS and EC, so their problems are different and they must be treated in isolation, a fix that could work for EXCALIBUR/KDE VII does not have to work for the EVO series

Regards

After extensive debugging of ACPI firmware crashes (touchpad freezes, system hangs, memory corruption), I'm switching this Slimbook VII to Windows 11 Pro with Arch in WSL2. The ODM chassis firmware appears optimized for Windows and remains unstable under Linux despite vendor support engagement. A recent failed boot after an update was the final confirmation that this hardware isn't production-ready for native Linux.

One week later, with Arch in WSL2 and very little use of the system due to constantly running fans (audibly spinning even at idle), I examined the BIOS and Windows 11 with 3rd-party tools. The Device Manager shows a Microsoft ACPI-Compliant Embedded Controller working properly, but the EC firmware itself is incomplete/defective. Windows just hides the problem better by not exposing errors, but the functionality is equally missing. Even under Windows 11 with ODM-targeted firmware, the EC does not expose any hardware monitoring data - the fans cannot be monitored or controlled.

BIOS: InsydeH20 0.13 (KPT-W042-FP8-0SLI)
OS: Windows 11 Professional Build 26200.7840

HWiNFO64 v8.40-5900 Report Analysis:
- EC device present in Device Manager (working properly)
- Zero EC sensor data exposed
- No fan speed monitoring available
- No motherboard thermal sensors accessible

Conclusion: EC firmware fundamentally broken for hardware monitoring,
independent of operating system. LibreHardwareMonitor and HWiNFO64
both fail to access sensor data. This is ODM firmware failure.

I'm hoping this cross-platform validation helps isolate the firmware issue for your ODM escalation. What's the timeline for a BIOS update addressing the EC sensor interface?

There has a new BIOS version been posted 3 days ago (v0.16), but I didn't hear anything from Slimbook support or in the forum. My machine runs still dual-boot Windows 11 (workable, no possibility to turn off the fans, no proper sleep/wake-support) and Ubuntu (occasionally freezes, no proper sleep/wake-support).

It has been since the end of December, that the KDE Slimbook VII is in this deplorable state (the sticker powered by GNU/Linux seems to be a joke).

Does anybody else have the same hardware and did already try to update BIOS V0.13 to V0.16? Unfortunately, there is no changelog in the download, so I don't know what this update addresses.

Hi maeschba.

Initially I too had had problems with the sleep functionality. However, the amd_iommu=off did the trick for me since I am using systemd-boot and the fix packages were for grub. Luckily , I did not experience the further issues you mentioned. I am also using Archlinux which I did installed my self. Did you tried the new BIOS version? I did try it and for me solved the sleep issue, I no longer need the amd_iommu=off kernel parameter. 

Best Regards

Hi David. Thank you for your notice. I did not try yet. Is there any chance that the fans stop spinning with the new release or is there always this constant low spinning, even if the system is idle? Are the dmesg errors regarding \_SB.ADP1._PSR gone? 

Suspend seems to work. dmesg only shows a problem with audio hardware and the cooling system is still a black box.

The most annoying part is that there is constant fan noise, even if the system is idle on TTY.

Hi maeschba. So far I had not noticed a lot of fan spinning, only on occasion. But you are right! They are spinning constantly but the sound was sow low I did notice. Even when changing modes. I'll check the bios but I am pretty sure I did not activate the fans always-on option. Regarding the ACPI logs mine seem to be fine, at least for the current bios:

Only the fans contant spinning seems to be the problem. That and DC offset pulse that causes that pop sound when they activate (only happens sometimes).

Best regards

[Update] It seems that there is no fan control option in the BIOS. I must have have confused with another device BIOS.

I do have similar output regarding audio:

The kernel detects AMD's ACP 7.0 audio hardware but a generic driver is covering for a missing machine driver. This doesn't really look like a Laptop genuinely built for Linux.

I can also confirm the pop sound that sometimes happens at startup.

This morning, my KDE Slimbook VII hard-crashed in Windows 11(!). This is the first or second time since I switched to dual-boot in February. Perhaps it's a coincidence, but Firefox is always in use just before a crash. I deactivated Firefox' hardware acceleration now in Linux and in Windows. 

Hello, @maeschba
Until the machine driver is not added here the kernel will still warn that it can't find a machine driver, it is a kernel issue and not hardware related, in any case the audio should work properly generally
As for the audio pops/crackling, you can follow the arch wiki troubleshooting section: https://wiki.archlinux.org/title/Advanced_Linux_Sound_Architecture/Troubleshooting
If there were any logs for the Windows crash, you could send them to see what truly crashed the device
