My system freezes after waking from suspend

[Christopher Sale]

I have installed Ubuntu 24.04 on my Lenovo ThinkPad T14 Gen 3 (AMD Ryzen™ 7 PRO 6850U with Radeon™ Graphics × 16). Type - 21CF-003QAU

Since installation, the following problem has occurred:

- Whenever I suspend the system (e.g. power off menu > suspend), the system successfully goes into a suspended state.
- When I wake the computer, the computer wakes and presents me with the login screen
- I can log into the system, and the mouse and all previously open windows appear to be working, sound is working etc
- I CAN'T seem to open any new applications or run any new commands at this time (no error messages, just nothing starting)
- Approximately 30 seconds to 1 minute later, the system freezes completely. No error messages, and I can see everything on the screen. But mouse/keyboard input stops, sound stops, and I have to physically hard restart the laptop.
- Example is caplock key light on keyboard stops responding. Interestingly the Esc/FnLock key light still works

I have updated all the firmware / BIOS to the latest versions, and the issue still persists.

I have run Ubuntu from a Live USB on the same machine, and when suspending, all appears to work OK.

I have done a completely fresh install with default installation parameters, and system freeze as explained above occurs every time.

After the last freeze, I ran journalctl -b -1 and attached is the output

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Martin Randau (cmmrandau)]

Identical behaviour here on a P14s Gen3 AMD. Suspend works, but it freezes seconds after logging in from GDM after resume.

[Martin Randau (cmmrandau)]

This problem does not seem to exist with the latest mainline kernel (6.10.3-061003-generic).

[Torsten Krah (tkrah)]

Same here. Freeze after resume on my Lenovo ThinkPad T14 Gen 3, model 21CFCTO1WW.

Additionally, with this 6.8.0-x kernel, I can no longer boot without my LID open and just use the docking station monitors. It boots, docking station is working (both displays are working) - I can enter my decryption password and after that it just continues to boot and goes straight into suspend mode.
6.5.x does not show this strange behavior.

Boot log has:

Thank you for taking the time to report this bug.

Would you be able to boot off of the Noble (24.04) USB install media, and select the "Try Ubuntu", and see if it reproduces with the kernel that is on the install media? I would like to know if this is a regression from when Noble originally shipped, or if it is older than that.

[Martin Randau (cmmrandau)]

I think that has been tried, as described in the first post: “I have run Ubuntu from a Live USB on the same machine, and when suspending, all appears to work OK.” :)

[Christopher Sale (christophersale)]

Yes, I am confirming that I downloaded the 24.04 LTS iso from the website, imaged it to a USB, and booted from it. When booting from the USB, the ubuntu installer opens by default. I closed the installer, which drops you into the live USB Ubuntu environment.

I clicked suspend from the power menu in the top right, and the laptop suspended without issue.

I woke the laptop, and the laptop woke without issue.

I continued to use the laptop for 5-10 minutes, and it did not freeze. Freezing from the installed version I have on my laptop now happens withing approx 1 min.

I am happy to boot from the live USB and run commands to get any version numbers or data you you need.

[Matthew Ruffell (mruffell)]

I think this is going to be fixed in 6.8.0-40-generic, currently in -proposed. You could try install it now and see if it fixes your issue. Let me know if it doesn't.

[Christopher Sale (christophersale)]

Hi,

I have installed 6.8.0-40-generic, and it appears to have resolved the issue. Thank you.

For the technically challenged like myself who are reading, here is how I installed it:

sudo nano /etc/apt/sources.list.d/ubuntu.sources
(Add "noble-proposed" to the end of the line "Suites:" under the archive.ubuntu.com URI)
sudo apt update
sudo apt install linux-tools-6.8.0-40-generic
sudo apt install linux-headers-generic=6.8.0-40.40
sudo apt install linux-generic/noble-proposed

Restart system

[Matthew Ruffell (mruffell)]

Great to hear it! Everyone else, hold tight, 6.8.0-40-generic will be released soon.
