FWIW your email prompted me to double check the two other Lenovo systems 
I have on hand at my desk:
* P14s Gen 1
* L14 Gen2a

One of them had a Ubuntu userspace (20.04 IIRC) and the other a Fedora 
38.  I built 6.6-rc3 and couldn't reproduce any issues with s2idle.

So yes; bisect is the next step, thanks.
