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.

I'm running stable/10:
