Hi there Yonetani,

I saw you were preparing an ACPI update. How far away are you from comitting it?

This may or may not be fixed by turning on the interpreter slack support; modify /sys/dev/acpica5/acpi.c as follows and rebuild the acpi.ko and reboot:

     * Set the globals from our tunables.  This is needed because ACPI-CA
     * uses UINT8 for some values and we have no tunable_byte.
    AcpiGbl_AllMethodsSerialized = (UINT8)acpi_serialize_methods;
    AcpiGbl_EnableInterpreterSlack = TRUE;	<== ADD THIS

I didn't commit this simple change apart because I saw the following note
in changes.txt in newer version of ACPI-CA source code:

12 May 2006. Summary of changes for version 20060512:

  1) ACPI CA Core Subsystem:
  Fixed a possible memory leak associated with the support for the
  so-called "implicit return" ACPI extension. Reported by FreeBSD,
  BZ #6514. (Fiodor Suietov)
