[ACPI] The system hang when setting ACPI_SYS_MODE_ACPI

[oco]

The system hang when setting ACPI_SYS_MODE_ACPI.

Unfortunately, my laptop does not have any a serial port. I cannot provide any debug output.

With some manual debug messages, i found that the system stop when writing ACPI_SYS_MODE_ACPI to jump into ACPI mode using AcpiOsWritePort. The caller's function is ACPIHWSetMode.

The system is in ACPI mode as the power button act like in this mode (i have to push it many second to stop the computer).

Under BeOS, ACPI is loaded correctly on this computer using an older ACPI module (when it was still compatible with BeOS, aka in late October 2006).

The problem is fixed in hrev23112.

I don't know who is credited for this fix. Maybe it is related to hrev23100.

This is a good news as i will be able to work again on my powernow! driver under Haiku.

OK, be sure to reopen if it happens again. Are you sure the acpi module was included in your build ?

Yes, the ACPI module is really loaded as i am even able to load my AMD64 driver. And it works (except timing problem) !

Here is what i can read in my Haiku syslog : ...
