            Bug ID: 292568
           Summary: ACPI S3 broken on CURRENT (Jan 2026)
           Product: Base System
           Version: 16.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: zarychtam@plan-b.pwste.edu.pl

After commit 7669cbd0f06402573fe627e9e6f86c69cfd3d12b (“acpi: Suspend-to-idle
support (s2idle)”), the system can enter the S3 sleep state only once.
Following the first resume, the system is no longer able to suspend again.
Reverting this commit removes the limitation and allows unlimited
suspend/resume cycles.
