RE: acpi_serialize not working?

[Moore, Robert]

The implementation of the forced serialization is straightforward:

    if (AcpiGbl_AllMethodsSerialized)
    {
        ObjDesc->Method.Concurrency = 1;
        ObjDesc->Method.MethodFlags |= AML_METHOD_SERIALIZED;
    }

I would be interested in more information on the failure.

I put some debug output into the code when "acpi_gbl_all_methods_serialized" 
is altered, an it seems that first the kernel parameters are parsed and 
acpi_gbl_all_methods_serialized is correctly set to TRUE but after that the 
global acpi variables are initialized and acpi_gbl_all_methods_serialized is 
set back to FALSE...

cool thx,
have tested 2.6.9-rc1 and indeed acpi_serialize is working now :-)

RE: acpi_serialize not working?

[Moore, Robert]

This was fixed, see below:

02 April 2004.  Summary of changes for version 20040402:

Moved the runtime configuration parameters from the global init
procedure to static variables in acglobal.h.  This will allow the host
to override the default values easily.

Please make sure you report that to ASUS, it's a BIOS bug and it should be
fixed by a BIOS update.

acpi_serialize not working?

[Andreas Dieling]

Hi,

i have an Asus M6N notebook. Me and other M6N users have the problem that the 
fan sometimes stops working which results in an overheating of the system. 
The problem occurs under Linux and under Windows.

After much investigation i could figure out the problem: 

It is a problem with concurrently appearing acpi events. If i am reading cpu 
temperature via acpi in an endless loop and the fan is switching on 
collateral the fan controll and temperature readout is crashing and left 
non-functional.

After i patched the dsdt and marked all aml methods as "Serialized" the 
problem doesn't occur anymore :-)

Since other M6N users may not want to patch their dsdt i tested acpi_serialize 
as a kernel option. I thought it should have the same effect, but it doesn't 
seem to work because the fan/temperatur problem occured again...

Is this a bug or has the acpi_serialize option a different purpose?

thx Andreas
