    Re: HOWTO Fix A Buggy DSDT File

    OK, here comes another one looking for help!! Not having found this thread, I started my own at and have followed a few red herrings. Basically my Intel DG965WH-based system has been running very hot since I upgraded from 8.04 to 9.04. I find that the fans are not picking up speed even when it gets hot. I am monitoring CPU and disc temps with sensor-applet.

    /proc/acpi/fans and .../thermal_zone are both empty.

    acpi -V returns just

         Cooling 0: Processor 0 of 10
         Cooling 1: Processor 0 of 10
    I've looked at the how-to at the beginning of this thread and like many others am petrified at what I see! But so far I have followed it as far as installing the iasl compiler and running it. I get just one warning:

    Intel ACPI Component Architecture
    ASL Optimizing Compiler version 20081204 [Jan 10 2009]
    Copyright (C) 2000 - 2008 Intel Corporation

    /home/xxx/dsdt.dsl  2187:                     Acquire (MUT0, 0x0FFF)
    Warning  1104 -                  Possible operator timeout is ignored ^ 
    ASL Input:  /home/xxx/dsdt.dsl - 5186 lines, 178431 bytes, 1615 keywords
    AML Output: /home/xxx/dsdt.aml - 15771 bytes, 546 named objects, 1069 executable opcodes
    Compilation complete. 0 Errors, 1 Warnings, 0 Remarks, 597 Optimizations
    which doesn't sound serious in itself, but I guess there may be other incorrect things in here that aren't errors.

    In the hope that someone might be able to help I'll attach a copy of the dsdt.dsl file ....

    Any pointers, clues or other assistance much appreciated!
