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.

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::00:14.0
even the USB bluetooth mouse won't be able to wake-
# grep . /sys/bus/usb/devices/*/product
/sys/bus/usb/devices/1-2/product:Wireless Device
/sys/bus/usb/devices/1-8/product:Integrated Camera
/sys/bus/usb/devices/usb1/product:xHCI Host Controller
/sys/bus/usb/devices/usb2/product:xHCI Host Controller
# grep . /sys/bus/usb/devices/*/power/wakeup
/sy
# grep . /sys/bus/usb/devices/*/product
/sys/bus/usb/devices/1-2/product:Wireless Device
/sys/bus/usb/devices/1-8/product:Integrated Camera
/sys/bus/usb/devices/usb1/product:xHCI Host Controller
/sys/bus/usb/devices/usb2/product:xHCI Host Controller
# grep . /sys/bus/usb/devices/*/power/wakeup
/sy
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
Device S-state Status Sysfs node

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

Title:
linux-image-5.15.0-27-generic causes Thinkpad T460p to not resum
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.

Also affects my T460.

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

apport information
** Tags added: apport-collected jammy
** Description changed:
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
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.
