Hi,

Having problems here with ACPI on Compaq Evo N610c laptop.
Everything boots up fine except when loading battery module
one gets this:

    ACPI-1120: *** Error: Method execution failed 
[\_SB_.C045.C059.C0E2.C13F] (Node c157bd40), AE_AML_UNINITIALIZED_LOCAL
    ACPI-1120: *** Error: Method execution failed 
[\_SB_.C045.C059.C0E2.C14E] (Node c157bc40), AE_AML_UNINITIALIZED_LOCAL
    ACPI-1120: *** Error: Method execution failed [\_SB_.C198._BTP] 
(Node c1577d20), AE_AML_UNINITIALIZED_LOCAL
ACPI: Battery Slot [C198] (battery present)
ACPI: Battery Slot [C199] (battery absent)

Tried with and without RELAXED_AML.

Now despite this machine seems to work fine until kde's laptop daemon 
does something I'm not aware of which results in
these lines in dmesg:

Aftwerwards whole KDE hangs (but that's probably KDE's problem) also 
trying to run 'acpi' on command line stalls and is not interruptible.
Shutdown stalls do.

Any solutions or something to try?
