Acpi_load_tables: Could not load namespace: AE_NOT_FOUND

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: Could not load namespace: AE_NOT_FOUND

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
