PC freezes insted of going to sleep

General system Kernel, boot, graphics & hardware

Hello,

I have had this issue for a few months, my PC is setup to sleep after 15 minutes of inactivity but it will inconsistently freeze instead of going to sleep. I have not figured out what makes it freeze so I can’t reproduce this, it just happens sometimes.

There is no output to screens, mouse and keyboard don’t seem to do anything (Numlock light stays on when I hit the key), can’t connect with ssh, REISUB doesn’t have any effect. I have to hold the power button to shutdown and reboot.

Here are some logs : inxi output, journalctl -b -1.

On this last log, sleep was supposed to be around 03:55 when there are the amdgpu errors (during those errors, power consumption dips about 50 W then goes back up after the log ends, then power becomes almost constant (+/- 0.5W) 7 minutes after that).

I update about once a week.

What can I do to diagnose the issue and resolve it ?

Thank you.

You need to disable secure boot in the bios.

Thank you, I thought I disabled it to install the OS but wouldn’t have thought to disable it for this problem anyway.

Hope that fixes your issue. Secure boot should be off anyway.

Hi @Stormweaker

Just had a look at your logs and I don’t think Secure Boot is the culprit here — your actual problem shows up around 03:55 when the system tried to sleep:

amdgpu: device lost from bus!
amdgpu: SMU: response:0xFFFFFFFF

Your RX 9070 XT is basically falling off the PCIe bus during suspend, and then the GPU’s power management chip stops responding entirely — hence the hard freeze.

There’s also this warning already at boot:

SMU driver if version not matched (driver expects 0x2e, GPU firmware is 0x33)

You own a very new GPU and the amdgpu driver is still catching up, especially around suspend/resume.

A few things you can try:

  • Add amdgpu.runpm=0 to your kernel parameters as a workaround (disables GPU runtime power management)
  • Keep an eye on kernel updates — RDNA 4 fixes are landing fast
  • For now you might just want to disable sleep entirely until a fix arrives

Also worth reporting on the AMD bugtracker with these logs, other 9070 XT users will thank you!

Good luck :eyes:
