DSDT compilation issues

DSDT compilation issues

[Martian67]

Hi, when i attempt to recompile a buggy DSDT table for my Toshiba P100
PSPA3C-MA502C, I get some compiletime errors, and i am not sure how to adress
them properly.

I am running through this procedure as outlined @
http://gentoo-wiki.com/HOWTO_Fix_Common_ACPI_Problems

**************************************************************************

cat /proc/acpi/dsdt > dsdt.dat

iasl -d dsdt.dat

iasl -tc dsdt.dsl

**************************************************************************

When I attempt to  do this it results in these errors

Hmm, I wonder why this is reserved, but renaming all instances of _T_0
to e.g. _TX0 or whatever should solve this?
Looks like a minor bug in the ACPI disassembler for me.

Remove the "*".

Could you explain why your DSDT is broken and what kind of bug you like
to fix.
To workaround ACPICA or DSDT bugs by simply overriding it is not a good
idea
as others might also slip into this. If possible, let's better try to
find a
general solution in the kernel/ACPICA code...

You also might want to open a bug report for your problem:
