Hi All,

Like a previous poster I am getting a lot of 1061 errors. Any suggestions for fixes?
Code:

Unfortunately googling has not helped on this occasion, so your pointers would be much appreciated.

I solved 1061 errors with CPU0 adding an external declaration
Code:
DefinitionBlock ("DSDT.aml", "DSDT", 1, "TOSHIB", "A000B   ", 537199409)
{
    External (\_PR.CPU0)

Hope this may help.

Thanks dgaffuri,

. . . but I don't know what is an "external declaration", or which external declaration would be appropriate in my case. Any suggestions?

Looking at the error I would say
Code:
External (\_PR.C000)

Wow! It worked! :D

Thank you dgaffuri. I managed to fix at least some of these 1061 errors. I entered the following two lines:
Code:
DefinitionBlock ("DSDT.aml", "DSDT", 1, "COMPAQ", "EVON600C", 0x00010000)
{
  External (\C001)                    <--------
  External (\_PR.C000)                <--------
    Name (C002, Package (0x04)
    {
        0x03,

which got rid of the errors:

dsdt.dsl 75: If (LEqual (\C001, 0x00))
Error 1061 - Object does not exist ^ (\C001)

and:

dsdt.dsl 6589: \_PR.C000
Error 1061 - Object does not exist ^ (\_PR.C000)

dsdt.dsl 6645: Notify (\_PR.C000, 0x80)
Error 1061 - Object does not exist ^ (\_PR.C000)

dsdt.dsl 6718: Notify (\_PR.C000, 0x80)
Error 1061 - Object does not exist ^ (\_PR.C000)

Here's where I am now:
Code:
# iasl -tc dsdt.dsl

I tried to enter an external declaration for \_SB.C03E.C052.C19E and the compiler came back with more than 200 errors!

What should I try next?

[EDIT:] I also tried to inc. the modified dsdt.hex into my kernel and it now fails as follows:
Code:
# make && make modules_install
  CHK     include/linux/version.h
  SPLIT   include/linux/autoconf.h -> include/config/*
  CHK     include/linux/compile.h

make[2]: *** [drivers/acpi/osl.o] Error 1
make[1]: *** [drivers/acpi] Error 2
make: *** [drivers] Error 2
The dsdt_table.h file is there alright, I checked:
Code:
]# ls -la /usr/src/linux-2.6.15-gentoo-r1/include/acpi/dsdt_table.h
-rw-r--r-- 1 root root 252490 Apr 15 19:33 /usr/src/linux-2.6.15-gentoo-r1/include/acpi/dsdt_table.h
I am not sure what's wrong. Is it meant to have zero errors or warnings for it to compile?
[EDIT/]

Thank you again for all your help.

Hi to all,
I have succesfully recompiled the DSDT but my system says "battery is absent" and the dmesg says:

I have a buggy DSDT too, unfortunately /proc/acpi doesn't exist, so I can't cat /proc/acpi/dsdt. I get the following acpi related messages during boot:

By using a patch that accepts the illegal 0x03 character (http://bugzilla.kernel.org/show_bug.cgi?id=6522) I was able to get ACPI working. It turned out that there were no other errors. My DSDT was compiled by the Intel compiler, according to MSI this one:

Intel ACPI Component Architecture ASL Compiler X2026 [Aug 31 2001]
Supports ACPI Specification Revision 2.0

which seems a bit dated as my version says:

Intel ACPI Component Architecture ASL Optimizing Compiler version 20060127 [May 8 2006]
Supports ACPI Specification Revision 3.0a

By replacing the illegal character by an 'S' I was able to decompile and recompile. I'm trying to get something definate on this illegal character from MSI, but their technical support seem to lack the requisite English and technical skills.

Hi,

I just bought an new laptop, and i am trying to fix some acpi problems but I don't understand
iasl errors

Code:

dsdt.dsl     1: ACPI And (Local1, 0xFF, Local1)
Error    4094 -    ^ syntax error, unexpected PARSEOP_NAMESEG, expecting PARSEOP_DEFINITIONBLOCK


The code seems correct, for exemple here is one method extract form a device section
Code:

            Method (SMBK, 1, Serialized)
            {
                ShiftRight (Arg0, 0x08, Local0)
                And (Local0, 0xFF, Local0)
                If (Local0)
                {
                    ShiftRight (Arg0, 0x10, Local0)
                    And (Local0, 0xFF, Local0)
                    ShiftRight (Arg0, 0x18, Local1)
                    And (Local1, 0xFF, Local1)
                    And (Arg0, 0x0F, Local3)
                    If (And (Local1, 0x01))
                    {
                        RBLK (Local1, Local0, Local3)
                    }
                    Else
                    {
                        WBLK (Local1, Local0, Local3)
                    }

                    Return (0x00)
                }
                Else
                {
                    ShiftRight (Arg0, 0x10, Local2)
                    And (Local2, 0xFF, Local2)
                    ShiftRight (Arg0, 0x18, Local1)
                    If (And (Local1, 0x01))
                    {
                        Return (DerefOf (Index (RBUF, Local2)))
                    }
                    Else
                    {
                        And (Arg0, 0xFF, Local1)
                        Store (Local1, Index (RBUF, Local2))
                        Return (0x00)
                    }
                }
            }


any ideas ?

Thanks in advance

Hey guys,

though, the last real answer is a little longer ago, I try to ask a little question in here. :P

This IASL now reports "Compilation complete. 0 Errors, 0 Warnings, 0 Remarks, 36 Optimizations". I'm wondering, what it does mean by "36 Optimizations". The Code should now be "fixed" (I had just this _WAK-bug), but IASL still reports this message. Can I turn on the optimization somehow? I did not find any option, but a option to disable it. I'm not sure, this message is showing up every time and just after recompiling the table, too. However, I'm using the new, recompiled table and thought the optimizations would stuck just in there. It seem they aren't.

Any suggestions?

different version of iasl produce different errors or NO ERRORS, what does it mean, try yourself

I see the same thing happen for my board's dsdt (ABIT GD8). I used to get errors but now the acpica-unix-20060707 version gets
Code:
dedeX compiler # ./iasl -tc dsdt.dsl

Older version of the iasl compiler was getting a few errors.

So would this generally be consistant with the current kernel and be working now?

I'd rather say yes, but keep in mind that the ACPI implementation in the Kernel is still somewhat experimental and far from being complete, though. Even if your DSDT is clean, there might remain some errors.

For me, Kernel 2.6.17 was changing the behavior when shutting down my Notebook - it's still not powering down properply, when I started a Desktop Environment like GNOME, KDE, FluxBox, BlackBox, XFCE (I'd rather say "when I did log-on in GDM"), but it's powering down, when I did not start any DE. X and GDM or the nVidia driver can't be the problems since it's powering down, when only X w/ GDM is running (but I don't have to log-in).

However, keep another thing in mind: modifing your firmware (-> your DSDT) can have unwanted "side effects", too. So, you might fixed one problem but this may _produced_ a lot more.
Also, no Kernel developer will help you with your problems, if you changed your DSDT since they may cannot locate the bug in the Kernel when it's hidden by an own DSDT.

You should try the following everytime before modifing anything:

    Get the latest Kernel (development there is quite fast)
    Get the latest video card drivers
    Get the latest BIOS from your manufactor - don't try changing anything in it
    Check, whether there are known issues with your version of X and the computer configuration looks similar to yours, or
    Get the latest version of X


These are things, that _can_ help with those issues.

spindle: I'm not sure about this, but if your mobo/your BIOS was quite new, it's common that older version of the IASL show errors, because there might be some ACPI calls the old IASL didn't know. Check this line:
Code:
Supports ACPI Specification Revision 3.0a

If this is also "3.0a" at the older compiler, it's time to worry. :P
But I think the supported ACPI version will be just lower then you might have.

And please, don't forget -> this guys are also just humans, errors might happen also to them.

Keep ACPI'ng.

Moderato: thanks for the helpful tips.

I just reverted to the default dsdt that the kernel gets from the mobo (kernel 2.6.16-gentoo-r12). I'll run like this for a while, and see if it fixes my possible overheating problem (I was seeing this issue before). I was running a modified dsdt, from an earlier attempt to fix a problem using the older 2005 IASL version. A while ago, I was trying to fix a problem with the termal reading on the CPU. It always said 40.0C and it still does anyway. I think your suspicion could be right, in trying to fix this problem I could have messed up some other important things in there.

The board is a fairly new model I think, from around summer 2005 I'm guessing (ABIT GD8). I'll check for a new BIOS too.

Hi spindle,

interesting issue. Are you running a Laptop?

You could also change to Kernel 2.6.17.6 for instance (as I said - for me better ACPI features and the new exploit got fixed, too).
Make sure you activited all the ACPI features in the Kernel, and, if you own a Laptop, double check whether you have implemented the thermal_zone (Symbol ACPI_THERMAL) and also check for those AMD processor "hacks" for detecting overheating, soft lockups and so on. Don't forget to enable verbose ACPI debugging in the Kernel. Even if you don't have a Laptop, enable them all.

If this still didn't help subscribe to the ACPI Mailinglist, search the ACPI bugzilla (it's also a Mailinglist) for the symptoms you observed.

In the case nothing helped and the bug is not known, send a bug report the Kernel development team or the Kernel ACPI team. (If you know, what you are doing, have really a lot of _useful_ informations towards this, also compiled your Kernel with frame pointers and unwind informations, have debug stacks, straces etc pp you could also directly send a bug report to the ACPI maintainer, but I discourage you from doing this, sending it to the Kernel guys will be fine, too, and quite more useful.)

So long, good luck.

[EDIT] By the way: I know this strange behavior of showing only "40.0C" as temperature from my Desktop, too. I'm not sure whether this is a DSDT bug or a Kernel/ACPI bug, I didn't fixed it, because I never had "real" thermal problems. I checked the DSDT of my Desktop computer and freaked out a little bit when I saw all these errors. Although, I never had problems with ACPI, so an error doesn't mean automagically that everything is b0rken in the ACPI implementation. :)
I also do not know how this bug behaves towards the THERMAL_ZONE which seems elementary. I'm worrying about this, now. But however, there might be some informative debug messages. [/EDIT]

No it's a desktop, also it's an Intel chip. The interesting thing about the 40 degree thing is that even though it's always at 40 degrees is the kernel (I think it's the kernel) is kicking out messages when the CPU core goes above a threshold and says it's throttling the CPU. But I think this is a signal or something that is coming from the BIOS.

Also it's interesting that when I'm running ut2004 that while I do get these messages oftentimes while playing but I never see unstability there or anywhere else in the system, for that matter. I only see this issue when I'm doing a emerge (and I think I've only seen it when it does a lot of packages in one shot). But doing a lot of compilation is probably even more cpu intensive that ut2004 or anything else I do on my system for long stretches so I guess that can still make sense.

I'm not completely sure this is a thermal issue, just seems the most likely at this point. It's pretty hard to tell if I can't read the temp on the CPU.

I think I'm going to take it slow and try the default dsdt for while and see what happens. I'll probably turn on those debug statements soon. If i still see the issue, I'll probably try that newer kernel.

Hi spindle,

ah, so I can assume we have ~the same CPU. (I got an Intel P IV 2998MHz in the Desktop and thus, the same issue.)

Yeah, playing UT2004 is NOT that CPU stressing - it's the GPU/your video card that might get really hot in this case, but the CPU is not under a real lot of load - in opposite to compiling...

Right, the BIOS is sending some messages about thermal throttling and it seems like you compiled this feature into the Kernel correctly. The bad news, however, is that this is REALLY bad. You should really search for a better cooling system. Your CPU is definitly way too hot. (Let me explain it like this... the BIOS needn't the Kernel for checking the temperature and therefore it's working fine just without it, although you cannot check the temperature via ACPI.)

I don't know whether the THERMAL_ZONE is working in Kernel 2.6.17.x correctly, but I assume the P IV just hasn't such ACPI informations.

For looking at the CPU temperature, I'd rather try lm_sensors. You need the I2C subsystem in the Kernel, if I remember correctly. Play with this program; it relates directly on the thermal sensor on your CPU.

In any case: I wish you good luck. And please, get a better cooling system. :)

[By the way: I also have some thermal issues on my Desktop with the P IV when playing games. In fact, the graphic card (ATI Radeon 9800 XT) is getting too hot and because my computer's case is almost small, freezes of the computer are happening, too. Even if I soft restart the computer it won't boot at all. Only after I let the computer cooling down everything works again. I think this happens because of the BIOS' thermal check.]

Yeah that doesn't sound good. I think I may try and re-apply the thermal compound on my current fan first. That fixed an overheating problem on an old box of mine a few years ago (with a cheap Intel fan). The fan on this box is a pretty nice zalman one. Hopefully that's the issue. I'd hate to buy another one, that one was pretty expensive.

Thanks again Moderato!

I'm using a Toshiba Satellite M40-141. I have never had the fan working with any Linux distro.
The DSTD was horribly broken, I couldn't even recompile it.

I found in the DSDT repository a good DSDT for my laptop (which has a Phoenix Bios, instead of a Toshiba one). I compiled it with no errors and no warnings.
It works greatly and now I can make the fan work.

But I have a REALLY BIG problem. If I try to play a sound (any sound) the computer hags (neither the mouse cursor moves) and I have to poweroff manually.

When I reboot I cannot find any useful logs about the crash.

Now I removed alsasound from my init scripts, and I'm using a soundless computer. But I'd really like to fix this.

Any ideas?

Are there even in dmesg no hints about Interrupts or somethings like this? Any conflicts?

I'd suggest trying the "noapic" and "nolapic" boot option first -- if it still crashes, we have to wait for other poeple and their ideas. :)
As an example: kernel /boot/vmlinuz-$something root=/dev/$yourdev noapic nolapic $theotheroptionsyouhave

Have a nice day.

Noapic and nolapic weren't useful. But I partially solved with acpi=noirq or irqpoll.

I don't know exactly what do those parameter mean, but now sound works. Anyway they give me some problems when I unplug and replug my ttyACM modem...

I'm trying to fix a dsdt on an Averatec 1020-ED1. My main reason for mucking around with this is that it seems the fan isn't running at all, nothing in /proc/acpi/fan. I followed the Howto but I can't get it to recognize my new DSDT.aml, dmesg keeps saying
Code:
ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found.


I tried copying DSDT.aml directly into /boot, and also tried making an image using cpio and gzip, same result. Tried to use mkinitrd but couldn't get it to work. I know that the patch says it now requires an initramfs image, but how do I create one and get it to recognize it?

Btw also tried the other patch for including dsdt in kernel and it wouldn't patch. Perhaps it is out of date or both can't be applied at the same time? This is on kernel version 2.6.16-gentoo-r13

Seems I was on the right track about the initramfs, so guess I'll answer my own question. Thanks go to Rob for his Tech Tip: How to use initramfs

Howto put DSDT.aml into an initrd image:

Make a directory, this will be the root of the image. Move the DSDT.aml file into this directory and change to it. Use find to list the files and pipe through cpio and gzip and output to the image file. For example:

Code:

mkdir image
cp DSDT.aml image/
cd image
find . | cpio -o -H newc | gzip > ../initrd-DSDT.cpio.gz
mount /boot
cp ../initrd-DSDT.cpio.gz /boot


Add this line to grub.conf after the kernel line
Code:

initrd /boot/initrd-DSDT.cpio.gz


Note that the line I put grub.conf doesn't have an = unlike the original howto. After I removed the equal sign and rebooted dmesg showed the image had loaded.

So now I have a slightly modified dsdt loaded. Still have yet to fix all the compile warnings. Not sure about the fan. Think messing with all this will fix it?
