The reboot problem appears in Linux too so it's likely that it's something acpi-ca is doing or not doing. Unfortunately, you have to write to pm1a/b to trigger a suspend so it's likely that the code does something wrong before then. Try commenting out various calls to _GTS, _PTS, and all the pm1a/b writes. Test each separately so you can see what each change does. I think someone found a system where calling _GTS actually triggered a sleep (non-standard). -- Nate
