My system should generally support s2idle well, but when running Intel’s S0ixSelftestTool (GitHub - intel/S0ixSelftestTool: S0ix Selftest Tool is designed to do the initial debugging for the S2idle path CPU Package C-state and S0ix failures in Linux OS for Intel® Client platforms, it also supports the basic runtime PC10 status check.), everything up to and including PC10 seems to work well, but there is no s0i2.0 or s0i3.0 residency, and from what I can see, there does not seem to be any apparent reason. I’m running Fedora 38, and the laptop is ASUS ExpertBook B5 Flip (B5302F). Here’s the log: https://paste.debian.net/hidden/7896ad07/
