power off issues (introduced btw 05/28/04 and 05/29/04)

[Phil Schulz]

Hi again!

  I tried to dig deeper and found out that the system started to behave 
incorrectly after the default of acpi_disable_on_poweroff was changed 
from 1 to 0 on 05/28/2004 at around 7:17 GMT. So I thought a solution 
might be to change it back to 1 but it seems that not only the sysctl 
but also the infrastructure behind it is gone in more recent versions of 
-stable.

  It seems that the system does OK until the call to 
AcpiEnterSleepState() in acpi_shutdown_final(), line 1611 of 
sys/dev/acpica/acpi.c Rev. 1.186.2.12 and then goes crazy.

  Going further with the infamous add-a-lot-of-printfs method I traced 
it until the call to AcpiHwRegisterWrite (ACPI_MTX_DO_NOT_LOCK, 
     ACPI_REGISTER_PM1A_CONTROL, PM1AControl) in AcpiEnterSleepState(), 
line 423 of sys/contrib/dev/acpica/hwsleep.c Rev. 70
  At that point, PM1AControl is 0x3c01

  I haven't bothered to look further since I don't really know what to 
look for. Is there anybody out there who could give me a hint? Does it 
even make sense to keep digging or is the hardware so horribly broken 
that there is almost no chance to fix it?

  The whole debugging process is kind of painfull since the stupid 
laptop does not have a serial port and the firewire device is already 
shut off at that point of the shutdown procedure so I don't have any 
debugger :-(

  Regards,

    Phil.
