Acpi_load_tables: Could not load namespace: AE_NOT_FOUND

Acpi_load_tables: Could not load namespace: AE_NOT_FOUND

[Bernd Pfrommer]

Hi,

after many fruitless attempts to get ACPI working with the 2.4.18 or 
2.4.19 kernel, I'm posting this in case somebody can help.
The hardware is an Intel manufactured SRMK2 server with a ServerWorks 
ServerSet IIILE chipset (CNB30LE North Bridge and OSB4 South Bridge), 
dual PIII 1GHz 256K cache, with 1GB memory. The bios is an AMIBIOS by 
American Megatrends Inc.

I configured the 2.4.19 kernel with the following parameters:

CONFIG_ACPI=y
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_BUSMGR=y
CONFIG_ACPI_SYS=y
CONFIG_ACPI_CPU=y
# CONFIG_ACPI_BUTTON is not set
# CONFIG_ACPI_AC is not set
# CONFIG_ACPI_EC is not set
# CONFIG_APM is not set

And I get the following errors during boot:

Sep 16 14:07:16 foo kernel:  tbxface-0099 [01] Acpi_load_tables      : 
ACPI Tables successfully loaded
Sep 16 14:07:16 foo kernel:  tbxface-0106: *** Error: Acpi_load_tables:

Sep 16 14:07:16 foo kernel:  utalloc-0598 [03] Ut_dump_allocations   : 
Total number of unfreed allocations = 5(5)

This may be similar to what Jean-Rene  Peulve posted earlier this year, 
but I could not find any replies to his posting
http://www.geocrawler.com/archives/3/17428/2002/2/0/7953806/ .

Although I configured for debug messages, the output of 
ACPI_DEBUG_PRINT() does not show up in dmesg. Does anybody know why that 
is?

Any suggestions what could cause the namespace loading to fail, and how 
to fix it?

Your help is greatly appreciated!

Thanks,

Bernd

Did you try fixing the DSDT table by hand?  There is a great page on
how to do this which was posted to this list recently.

http://www.cpqlinux.com/acpi-howto.html

Basically you dump the table into AML source and then recompile it
using Intels AML compiler.  Intel's compiler is more strict and
catches errors which Microsoft's does not.  The page has many good
tips on how to fix up broken AML code.

Once it compiles clean there is a small patch to 2.4.19+acpi to read
the table from a file. (the intel aml compiler outputs a hex table as
C code).

I did this and it some missing features magically reappeared (like the
ac-adapter and the battery).

might be worth a shot...  seems like some/many/most DSDT tables have
bugs.
