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).
