linux-image-5.15.0-27-generic causes Thinkpad T460p to not resume after suspend

[Sebastien G]

After upgrading from Ubuntu 21.10 to Ubuntu 22.04, my Lenovo Thinkpad T460p doesn't wake-up after suspend. The kernel installed was linux-image-5.15.0-27-generic. I downgraded to Linux kernel 5.13.15 and it works fine now.

With Ubuntu 21.10, I had linux-image-5.13.15-40-generic kernel and it worked fine, but I've uninstalled it after the upgrade to 22.04.

I also tested newer versions like 5.16.x and 5.17.x with the mainline program and they cause the same issue.

The issue is that no key nor the power button nor the screen lid wake the laptop with kernel versions superior to Linux 5.13 (5.13.15 I think).

It's either a Linux kernel problem, or a compile options mistake.

[Sebastien G (turbocharger007)]

I've just tested Manjaro Live CD on the same laptop (Lenovo Thinkpad T460p) and the resume works well with kernel 5.15.x so it's a kernel configuration issue from Ubuntu.

I have the same resume issue with mainline kernels 5.16.20 and 5.17.5

[Sebastien G (turbocharger007)]

The resume after suspend works with Ubuntu mainline kernel 5.14.16. So the issue occurs with 5.15.x kernels.

[Sebastien G (turbocharger007)]

In fact, the issue occurs with all kernels starting from 5.15.x and newer versions. 5.16.x, 5.17.x too.

[cuby (cuby)]

Also affects my T460.

[Sebastien G (turbocharger007)]

The Lenovo Thinkpad T460p has 3 ways to resume the laptop after suspend : the screen lid button (when we open up the screen), the power button and the Fn key on the keyboard. All of them work with kernels up to 5.14 on Ubuntu, and none of them work with kernels starting from 5.15 and upwards.

[Manuel Pégourié-Gonnard (mpg)]

Same here with my ThinkPad E460. Everything was working fine with 20.04.

[Manuel Pégourié-Gonnard (mpg)]

I tried version-bisecting the issue using the mainline kernel ppa, as in https://wiki.ubuntu.com/Kernel/KernelBisection#Version_bisecting_upstream_kernels

The last good version is 5.14.20.

The first bad version is 5.14.21.

Just to be sure this hasn't been fixed in the meantime, I tried 5.18-r6 and it's still bad.

[Manuel Pégourié-Gonnard (mpg)]

I tried commit-bisecting the issue, but the build instructions are not working for me.

However, I'd like to point out that there are only 15 commits between 5.14.20 (working for me) and 5.14.21 (not working for me). https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-5.14.y

[Sebastien G (turbocharger007)]

I have what is maybe the beginning of a solution : I was able to disable my USB bluetooth mouse to wake-up my Lenovo Thinkpad T460p by doing this :

# echo XHCI > /proc/acpi/wakeup

# cat /proc/acpi/wakeup

Note that there is no external USB devices plugged-in except the USB dongle of my Bluetooth mouse.

(That's outpout with the kernel from the linux-image-5.15.0-27-generic package)

[Sebastien G (turbocharger007)]

I needed to disable my USB bluetooth mouse to wake-up my Lenovo Thinkpad T460p with mainline kernel 5.14.16, but if I redo "# echo XHCI > /proc/acpi/wakeup" with the kernel 5.15.0-27-generic and it prints this :

XHCI S3 *enabled pci:0000:00:14.0

even the USB bluetooth mouse won't be able to wake-up the laptop. I have the exact same issue with newer kernel 5.15.0-33-generic from the current linux-image-generic package.

But the problem is solved using mainline kernel 5.18.0!

[Manuel Pégourié-Gonnard (mpg)]

After seeing the previous comment, I decided to try 5.18, so I installed 5.18.2 from the mainline ppa and it fixes the problem for me as well.

[Sebastien G (turbocharger007)]

Yes, but using the 5.18 kernel from mainline makes me impossible to use the Ububntu delivered VirtualBox, so I don't use it. I stick with 5.14.20 from mainline. So there's no real solution to use a newer kernel for now.

[Manuel Pégourié-Gonnard (mpg)]

I'm happy to report that the problem seems to be gone with the 5.15.0-40-generic kernel. I've been able to suspend and resume two times since booting it.

Maybe you should give it a try? If 5.15.0-40 fixes it for you as well, then it probably means this bug can be closed.
