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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2080693 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.
