Acpi on compaq N620C

Hi,

I'm trying to get ACPI working on a Compaq Evo N620C.

Whatever version of the kernel i try (2.4.22, 2.6.0-test[89]) i'm getting these messages at boot:

ACPI: Subsystem revision 20031002
ACPI: IRQ 9 was Edge Triggered, setting to Level Triggerd
ACPI: Interpreter enabled
ACPI: Using PIC for interrupt routing

    ACPI-1120: *** Error: Method execution failed [\_SB_.C046.C052] (Node cffbdc40), AE_AML_BUFFER_LIMIT
    ACPI-1120: *** Error: Method execution failed [\_SB_.C046.C056] (Node cffbdc20), AE_AML_BUFFER_LIMIT
    ACPI-1120: *** Error: Method execution failed [\_SB_.C046._CRS] (Node cffbdc00), AE_AML_BUFFER_LIMIT
    ACPI-0098: *** Error: Method execution failed [\_SB_.C046._CRS] (Node cffbdc00), AE_AML_BUFFER_LIMIT

ACPI: PCI Root Bridge [C046] (00:00)

Despite this message, ACPI *seems* to work

I can load modules processor, thermal, ac, fan & button without errors

'modprobe battery' gives:

    ACPI-1120: *** Error: Method execution failed [\_SB_.C046.C059.C0E4.C153] (Node c12c2940), AE_AML_UNINITIALIZED_LOCAL
    ACPI-1120: *** Error: Method execution failed [\_SB_.C046.C059.C0E4.C162] (Node c12c2840), AE_AML_UNINITIALIZED_LOCAL
    ACPI-1120: *** Error: Method execution failed [\_SB_.C1B1._BTP] (Node c12c0c40), AE_AML_UNINITIALIZED_LOCAL

ACPI: Battery Slot [C1B1] (battery present)
ACPI: Battery Slot [C1B2] (battery absent)

Now, it gets worse:

I often have two progs reading battery level: gkrellm and wmbattery. I can't tell when this happends exactly (mainly if I switch from console to X) but these processes frequently get stuck in "D" state.

If I try acpi sleep functions the screen goes black and nothing will get it back (I need to force hard reboot 2 times)

I do not know well ACPI, but i'd like to help if it is possible ... just tell me how.
I have dumped all infos (using acpidmp, dmidecode, iasl etc.) but as it is quite big i've not attached it to this mail.

Thank you for your help,

/P

We're on Token Ring, and it looks like the token got loose.
