trouble overriding DSDT

[Sascha Klauder]

Hi,

 I'm trying to fix the DSDT of my HP nx9005 (running 5.3-BETA4)
in hope of getting suspend/resume functionality to work (it does
suspend (S3), but not resume).

This is what I did (following chapter 11.16 in the handbook):

 # acpidump -t -d > nx9005-KA.M-1.59-original.asl
 $ cp nx9005-KA.M-1.59-original.asl nx9005-KA.M-1.59-custom.asl
 $ joe nx9005-KA.M-1.59-custom.asl
 $ iasl nx9005-KA.M-1.59-custom.asl
 # cp DSDT.aml /boot/

and adding the necessary statements to /boot/loader.conf to get
the custom DSDT loaded.

Now, upon rebooting, I get the following error:

 ACPI: DSDT was overridden.
   ACPI-0374: *** Info: Table [DSDT] replaced by host OS
   ACPI-0380: *** Error: Looking up [_PCT] in namespace, AE_ALREADY_EXISTS
   ACPI-1303: *** Error: [NULL NAME], AE_ALREADY_EXISTS

followed by a kernel trap.  Could this be a problem with iasl or
did I missed something else? 

Cheers,
