DSDT/ASL compiler error

[Ben B <kernel@bb.cactii.net>]

Wondering if any ASL experts can help me here. I'm trying to recompile
the DSDT on my HP NC6400 laptop, to hopefully get some better acpi
functionality, and I'm seeing the following error:

$ iasl -tc dsdt.dsl

The relevent section around line 12767 is this:

            Return (^^C1AD.C1D2 ())

What suggestions does anyone have on fixing this?

Thanks,
