[Bug 2080693] Re: Not resuming from suspend - Thinkpad E460

For what it's worth, the problem persists with the 6.8.0-48-generic
kernel.

Also, I've tried building the kernel locally in order to hopefully
commit-bisect the issue. Turns out my locally compiled 6.6.19 does not
exhibit the problem, while 6.6.19 from the mainline kernel ppa does.

I've done the following changes to the config:
1. make localmodconfig (to cut on compilation time and disk usage)
2. scripts/config --disable SYSTEM_TRUSTED_KEYS && scripts/config --disable SYSTEM_REVOCATION_KEYS (I was getting errors about files not being found)
3. disabled CONFIG_DEBUG_INFO_BTF because I was running out of memory at that stage
4. disabled zstd module compression because I was getting errors like `SSL error:10000080:BIO routines::no such file: ../crypto/bio/bss_file.c:7` at the stage where the modules are signed.

I'm not sure which of these changes is likely to explain why my locally
compiled kernel works while the one from the ppa doesn't (as far as
waking up from suspend is concerned), but I thought I'd share the info
in case it rings a bell to someone.

Title:
Not resuming from suspend - Thinkpad E460

Status in linux package in Ubuntu:
Incomplete

Bug description:
After a routine upgrade which installed the 6.8 kernel, my laptop
(Lenovo Thinkpad E460) stopped resuming from suspend. I press keys,
hit the power button, but nothing works and I have to hard reboot in
the end.

Everything worked nicely with the 6.5 kernel (6.5.0-45-generic) and
previous versions provided by Ubuntu since 5.15.0-40-generic (before
that I was hit by
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971437 with
similar symptoms).

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 6.6.18.

The first bad version is 6.6.19.

I'm happy to provide any further information that might be useful.
