Bug Description

Recently my Lenovo ThinkPad W540 laptop has been unable to suspend correctly. It immediately wakes up after going through all the usual steps of turning off the screens, USB devices etc.

I'm using the UI to suspend by left-clicking and holding the power off button until it turns into a pause button, and then I left-click that button. The laptop is docked with two monitors connected and the lid is open (although the laptop screen is not used) when I attempt to suspend it.

This used to work until recently. BIOS has not been touched or upgraded.

Sounds like it's a regression? Can you please find the last kernel that works?

Older kernels have sadly been purged before I became aware of this. If I can get older kernel packages I'm willing to try to find the last version that worked.

Right now I'm using linux-image-generic-hwe-18.04 (= 5.0.0.23.80) and have the same issue.

Oddly, if I enable pm_trace (echo 1 > /sys/power/pm_trace) then I'm able to suspend and resume correctly.

I was searching why suspend is not working anymore with 5.0.0-23 for me and found this similar bug.

Sometimes it is coming up again after trying, sometimes it freezes. I tried the echo cmd from #20, no difference for me.

But with 4.15.0-55-generic it works for me (unlike the initial report if i understood it correctly)

I have a Lenovo P52, let me know if you also want a full report.

update: i had some time and did a fresh installation of Xubuntu 18.04.3 on an USB SSD. Suspend works with Kernel 5.0, first i suspected the nvidia driver but it still works after installation of the nvidia drivers. So for me it is either a setting which i'm not aware of that is different or the main difference between these 2 installation: my Laptop runs zfs root, the USB installation is simple ext4.

I still have the issue with linux-image-generic-hwe-18.04=5.0.0.25.82.

Please test latest mainline kernel:

5.3.0-050300rc4-generic was slower to suspend but the same happens. The laptop is suspended less than a second and just enough to see the fading powerlight indicating sleep mode before it resumes.

Then it's not fixed in upstream.
Please find the last good kernel and first bad kernel in https://kernel.ubuntu.com/~kernel-ppa/mainline

Only need to test -rc* kernels.

I've now tested kernels 4.15.0-39, 4.15.0-45, 4.15.0-50, 4.15.0-54, 4.15.0-55 and all have the same behaviour - so this does not seem to be a kernel issue after all.

I unplugged everything and tested suspend/resume on 5.0.0-25-generic which now works. Tested suspend/resume after each device was reconnected and identified the keyboard as the reason it resumes. Tried disabling all USB (XHCI/EHC*) in /proc/acpi/wakeup without success. Finally moved the keyboard to another USB port (non-SS) in the dock and I am now able to suspend without it waking up immediately.

Does change "power/wakeup" help?

I've replaced the keyboard and I'm not experiencing the issue on the USB port as I did with the old keyboard (only tested on the 5.0.0-25 hwe kernel). Not sure what could be causing that behaviour all of a sudden. The old keyboard (Logitech) didn't appear to have any noticeable issues such as a stuck key or something that might trigger a wake-up.
