    I attach all dsdt files, as well as dmesg output file.

    Thank you so much!!
    I fixed the warnings. I had to put a return value for the PSR method.

    Re: HOWTO Fix A Buggy DSDT File

    thanks a lot. Later today I'll try your DSDT and report back.

    Do you know if that should make any effect to how stuff works? Or was is just a simple and no harmful warning?

    (_PSR) has to do with your power source. I would check to see if the battery shows charge/discharge correctly. The method already had the values 0x00(off) and 0x01(on), but needed a null value in case no value was returned. You really shouldn't notice any difference.

    I'd sure give it a try. Ubuntu-Intrepid-64 bit...Hard to argue with that one. Apparently toshset/toshutils are related, one gui one cmd line.
    Ok my problem seems to be resolved..

    The above post and 67GTA's previous post mentioning that Toshiba's seem to have trouble with linux got me thinking... whether it was simply related to a bad (ie buggy ) acpi implementation in Hardy.. Toshset wouldn't run complaining that it was an unsupported Kernel extension...

    So this morning I decide to can the entire distro and downloaded 9.0.4 (jaunty jackaloupe) and had it installed in about an hour or so.
    The install went pretty smoothly and the temps were distinctly lower.
    So the laptop doesn't seem to be overheating as of now ie 6 hours later..

    Here is the output from acpi..

    peter@neutrino:acpi -V
    Battery 0: Charging, 35%, 00:57:48 until charged
    Battery 0: design capacity 4000 mAh, last full capacity 4254 mAh = 100%
    AC Adapter 0: off-line
    Thermal 0: ok, 49.0 degrees C
    Cooling 0: LCD 3 of 7
    Cooling 1: Processor 0 of 3
    Cooling 2: Processor 0 of 10
    Cooling 3: Fan 1 of 1
    peter@neutrino:~$ acpi -t
    Battery 0: Charging, 36%, 00:56:54 until charged
    Thermal 0: ok, 49.0 degrees C


    With Hardy on this laptop the temps start at about 60 C and keeps rising to 75 or so.. I stop the machine at that point.. No point frying eggs with the laptop...

    Thanks for all the understanding regarding DSDT's and ACPI ( both are totally new areas for me... )

    Re: HOWTO Fix A Buggy DSDT File

    67GTA, you look like a god send to amny people so thanks in advance

    Anyway, I have an Acer Aspire 5520 and I'm having heating issues.. I have fixed as much as I can with the dsdt file, but I'm right at the edge of what I know about linux here and there are still more warnings that I want gone when I try to compile.

    And attached is the file itself, let me know if you need anymore info from me thanks, you really are awesome for helping with this issue.

    As an aside, I do NOT have anything listed in proc/acpi/fan/ folder. I did the thing you had told peterwill to do with the command:

    Code:
    sudo sensors-detect
    Output of sensors:

    Code:
    acpitz-virtual-0
    Adapter: Virtual device
    temp1:       +66.0°C  (crit = +100.0°C)

    Core1 Temp:  +64.0°C                                    
    Core1 Temp:  +63.0°C
    It gets really hot and the fan doesn't kick on as fast (or as loud) as it does in windows playing the same game. I'm looking at 85°C+ temps during gaming and I would like the fan to kick on sooner and be able to spin faster as it does in windows.

    Thanks again

    Re: HOWTO Fix A Buggy DSDT File

    Hey there! I was recently fascinated by this post about two weeks ago, when I wanted to figure out the issues behind a misplaced IRQ, and why my laptop wasn't idling cool enough (54C idle is NOT cool, man).

    I did some digging (after reading your and everyone else's post), and I managed to find some documentation for ASL here: http://acpi.info/spec.htm . Be forewarned - those without any programming experience or assembly experience will be lost in some places.

    I've learned a handful from debugging the DSDT file, including how it controls certain resources (hence my wireless card dying sometimes). So far, with your guide, I was able to knock my laptop's idle down to about 41-47C w/o AC and about 36-43C w/AC.

    I hope that the documentation (I'd use the PDF) will help you and everyone else looking to disect their DSDT, and hopefully it will ultimately lead to an improved experience with fan control, thermals, and hibernation.

    Re: HOWTO Fix A Buggy DSDT File

    I have a Raon Digital Everun Note D60H with a factory underclocked Turion X2-TL56 @ 1200MHz. I have a DSDT bug (error 4095) and powernow-k8 doesn't work (see dmesg).
    Thanks a lot for a fixed file.

    Stupid Microsoft Compiler. If we don't use any of their crappy OSes they just f*** up the BIOS.

    Re: HOWTO Fix A Buggy DSDT File

    Hello,

    Seems like some of you have really screwed up dsdt s . Mine is not that bad, just 1 warning. Having said that I haven`t got a clue about how to fix it. I googled, read some other threads and found other people with similar problems but no solution.

    Some help would be greatly appreciated.

    Re: HOWTO Fix A Buggy DSDT File

    Sorry, I've been busy with work. I haven't checked my email for several days.

    jijin: I have dealt with several Acer Aspire's and can not effect the temp through the BIOS. I have advised everyone to file bugs against acpi, pm-utils, or maybe kernel (not sure) for their laptop model. I have fixed the errors for yours.

    dsdt.aml.jijin.zip


    Schugy: I didn't see any errors pertaining to your problems. Hopefully the Intel compiler automatically fixed them. It made around 1400 optimizations by it's self. If not, we can investigate.

    dsdt.aml.Schugy.zip


    ubunxpm: Yours was hiding. I fixed the 1 error, and 8 more showed up(LOL). I fixed them, and the Intel compiler still made about 2500 optimizations.

    dsdt.aml.ubunxpm.zip


    Be sure to add the acpi_osi="Linux" description per the how to. Send me your dmesg outputs afterwards, and I will check to see what is happening.
