I have several issues with acpi after a suspend/resume cycle, that I don't have after a fresh boot: - hw.acpi.acline is stuck on whatever was the case during resume, this affects c-states, powerd and battery status display. - I often have (measurably) low performance when AC powered, independent of what hw.acpi.acline says. I need to plug it out and back in, sometimes multiple times to get the expected performance. - Scrolling content and playing videos is jerky. - Keys that are reported as ACPI events do not work anymore, most noticably the sleep key. Keys that bypass the OS (e.g. screen blank, touchpad and camera on/off) still work. So do keys that are reported as keyboard events, e.g. volume up/down.
