Help! After 2025-08-12 updates, suspend no longer works on my Thinkpad T14

General system Kernel, boot, graphics & hardware
1

I’m running EOS/Cinnamon on a Thinkpad T14 Gen 1, and suspend, suspend-then-hibernate, hybrid-sleep and hibernate have been working fine for weeks.

I typically don’t shutdown this laptop for days, just close & reopen the lid 30-40 times a day, and sometimes connect it to the AC adapter to recharge it.

I didn’t:

  • install new software
  • play around with power settings
  • change any system settings

I did:

  • do normal updates a few times per day (using yay)
  • check & write in forums a lot

Now, since yesternight (2025-08-12), the system suddenly fails to suspend, and resumes immediately, asking me to login again (using cinnamon-screensaver).

BIOS is set for S3 (“Linux”) instead of S2idle (“Windows”). I have a separate swap partition (for hibernate).

$ cat /sys/power/mem_sleep 
s2idle [deep]

$ cat /sys/power/state 
freeze mem disk

$ cat /sys/power/disk 
[platform] shutdown reboot suspend test_resume

$ cat /sys/power/image_size 
6551207936

$ lsblk

With the information at hand, I would normally suspect the USB 3.1 at PCI 00:14.0, but nothing is connected there. I even disconnected the AC adaptor (USB-C) since I thought it might be “talking” via USB. Also note the several messages in the journal stating … was not an MTP device, but these are in the log since 2025-07-27.

I did have my Pocketbook e-reader connected to USB in the evening, to transfer a book to it using Calibre. But that was long disconnected again before the update at around 22:30 yesterday.

(I also didn’t see any AUR error messages yesterday, as some others have reported.)

Help, please…

Interesting: I just tried a systemctl hibernate, and that works fine!

Not a solution to the original problem, of course.

I had something similar where the computer would sleep and then immediately wake up again. It was my wireless mouse constantly sending a signal.

I solved it with this systemd service:

[Unit]
Description=Disable USB Mouse wakeup triggers

[Service]
Type=oneshot
ExecStart=/bin/sh -c "echo XHC0 > /proc/acpi/wakeup"
ExecStop=/bin/sh -c "echo XHC0 > /proc/acpi/wakeup"
RemainAfterExit=yes

[Install] 
WantedBy=multi-user.target

Thanks for showing one way to solve such issues, and for reminding me of bluetooth devices.

I actually have two devices trusted (my headphones and a BT keyboard for testing) but not connected, and I’m sure these were turned off.

$ journalctl -u bluetooth

indeed shows no irregularities.

But it gets “curiouser and curiouser”: After leaving the laptop in hibernation after above tests for a few hours, now suddenly suspend seems to work again. Needs a few more tries to be sure, though.

I wonder what’s going on here. Ghosts?

And yes, I did also try a complete shutdown before, waiting a few minutes, and restarting the system, and suspend wouldn’t work.

There’s only two more ideas I have—could that have confused the suspend/resume system?

  • It’s possible I connected the (USB-C) AC charger while it was in suspend mode. I must surely have done that before, and it shouldn’t matter (hopefully).
  • I use the built-in fingerprint reader, and the Arch docs say somewhere one shouldn’t suspend/resume again within 30s. I might have inadvertently done that, but chances are almost nil, since I know about that issue.

I agree that they shouldn’t affect it but sometimes I swear that computers like to mess with our heads.

Having something work and you don’t know why is even worse than having it not work and you don’t know why…

Now let me shutdown and then try to suspend again after a restart… This machine is used to do actual work and thus should be most reliable.

I must also re-test the suspend-then-hibernate—would you know offhand where to set the hibernation timeout? (It’s supposed to react on battery level and a settable “in suspend mode for” time, as far as I remember.)

Never mind, found it. Set HibernateDelaySec=300 in /etc/systemd/sleep.conf for a test (it’s normally 60min on this system), and invoked systemctl suspend-then-hibernate.

All good, RTC wakeup functions, system suspends, wakes up after 5 minutes and hibernates. When powering on again, it resumes fine from hibernation state.

Love that functionality. If ever I just suspend my laptop and then forget it, it’ll auto-hibernate when either a) the battery goes below 5%, or b) the HibernateDelaySec runs out, whichever comes first.

Linux is indeed a very fine system to work with.

Worked for a while, now after the kernel 6.16 updates immediately resumes again!

Since we already saw it’s caused by the USB3 ACPI for some reason (xhci_hcd at PCI 0000:00:14.0):

Aug 17 22:43:42 t14-mch kernel: xhci_hcd 0000:00:14.0: PM: pci_pm_suspend(): hcd_pci_suspend returns -16
Aug 17 22:43:42 t14-mch kernel: xhci_hcd 0000:00:14.0: PM: dpm_run_callback(): pci_pm_suspend returns -16
Aug 17 22:43:42 t14-mch kernel: xhci_hcd 0000:00:14.0: PM: failed to suspend async: error -16
Aug 17 22:43:42 t14-mch kernel: PM: Some devices failed to suspend, or early wake event detected

I dont’t need the system to be woken up by something on the USB3 port, so I took more drastic measures and disabled it:

# /etc/tmpfiles.d/disable-usb-wake.conf
# Disable PCI 14.0 XHC USB wakeup (prevents suspending)

#    Path                  Mode UID  GID  Age Argument
w    /proc/acpi/wakeup     -    -    -    -   XHC

Result after each boot/resume:

$ cat /proc/acpi/wakeup 
Device   S-state    Status  Sysfs node
XHC        S3    *disabled  pci:0000:00:14.0

Seems to work: suspend, suspend-then-hibernate, hibernate and hybrid-sleep all working for now.

The little things take the most time to fix.

that certainly handicaps any troubleshooting :slight_smile:

what did the numbers do? force systemctl to stop suspend service?

9

Which? The HibernateDelaySec=300 just sets it to 300s (5min), so I didn’t have to wait an hour after suspending in order to check if it wakes up again, saves RAM to disk and goes to hibernate. I reset that back after testing. It then goes to hibernate after 1 hour of being suspended or when the battery goes below 5%.

10

I get it now.

what an adventure this was. all your troubleshooting moved in a positive direction…it’s like you’ve done this before :slight_smile:

Yep, this lil Thinkpad was just too good to give up on it. I love it more every day (the keyboard is so fantastic!) and don’t regret a minute having put EOS instead of Mint on it.

Done this before? Well, not exactly this, but it helps having been in IT for more than 50 years. Once you grok how Linux works, they’re all pretty much the same underneath. Just the packaging and WMs/DEs differ a little.

Also, doing a little bug-hunting keeps the brains working, always good at my age! :grin: And the Arch Wiki is a tremendous help.
