ACPI 2.4.25/20040211 on Acer TravelMate C100

Dear list,

unfortunately with Linux 2.4.25 (even with the most up to date patches to 20040211) ACPI stopped working on my Acer TravelMate C100.

It worked fine with 2.4.23 with 20031002, but now all i get is:

---=== cut here ===---
BIOS-e820: ............... - ................ (ACPI data)
BIOS-e820: ............... - ................ (ACPI NVS)
.
.
.
ACPI: have wakeup address 0xc9991999
.
.
.
ACPI: RSDP (v000 Acer ) @ 0x000ec2d0

.
.
.
---=== cut here ===---

up to here it's equivalent to 2.4.23/20031002, but

---=== cut here ===---
.
.
.
ACPI: Subsystem revision 20040211
ACPI: Interpreter disabled.
.
.
.
PCI: ACPI table contains no PCI IRQ routing enteries .
.
.
---=== cut here ===---

I've traced this to line 2037 of drivers/acpi/bus.c, in acpi_init (void) but now I'm stuck.

I've tried the commandline parameters acpi=force (with debug) and have

CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_RELAXED_AML=y

(and the rest of the ACPI stuff on either 'y' or 'm', actually except this two options the same config as with 2.4.23)

Can anyone give me a pointer on how to procide?

BTW: Sorry, but I'm not on the list so please CC me.

Thanks,
Goetz.

This looks like the same problem as:

I don't know if the patch I did against 2.6.3 will be any use...
