I don't think this is a bug.
It just suggests that S3 is not supported on this platform.

These are CPU cstates, and these messages show there are 3 ACPI Cstate
supported, so this is not a bug.

TBH, I don't think so.
May I know is it
windows on modern Intel platforms usually uses s0ix as system low power state,
and Linux s2idle does the same thing.
Bug closed as I don't see any problem from the description above.
But if there are some issues like high power consumption during system sleep,
then that sounds like a real issue and feel free to re-open this bug report.
