I'm on -current #168 (Thu Jul 4 18:00:50 MDT 2024) and I cannot suspend (sleep) my computer using zzz. When I run zzz, the screen enter power save mode, the machine seems to be sleeping: the lights on the power button goes blinking for 2s, and then the machine wake up.
The machine is Dell Optiplex 9020 CPU: Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz I started apmd without flag.
