differences between acpidump and disassembling dsdt with iasl

differences between acpidump and disassembling dsdt with iasl

[Emilio Mejía Fernández de Velasco]

Hello,
I'm having many problems to run acpi in my laptop. The last one came when I 
tried to fix the dsdt table. I found one error and fixed it. There were some 
arguments missing in DefinitionBlock, so I added them.
After fixing the dsdt and rebooting, I get different files from acpidump than 
rebuilding /proc/acpi/dsdt with iasl -d
In fact, this last method is the one that doesn't give errors after the 
fix-up. Yet acpidump doesn't seem to notice the fixing, because it still 
gives a file with the same arguments missing.
The problem is that I can't get my kernel working with acpi. It freezes after 
some time working. The keyboard doesn't respond and so I have to reboot. 
There is no message reported in /var/log/messages so I don't know where the 
blocking comes from. What I can see for example is that when I unplug the AC 
adapter a couple of times then I get it blocked automatically. Otherwise it 
gets blocked after some time anyway.
Now I have my system working with apm and it is stable, but it is not able to 
give an IRQ to the network card, and there are some other things that only 
work when I compile the kernel with acpi. Everything else is much better with 
the acpi kernel, except for the inconvenience that it breaks down after some 
minutes working.
Has anyone experienced similar problems? 
Is there any way to trace the errors and find where they come from?

This is the error when I try to compile the file returned by acpidump:
dsdt.asl    35: {_SB_.VIAX(0x8a)
Error    1037 - ^ parse error, unexpected '{', expecting PARSEOP_INTEGER

ASL Input:  dsdt.asl - 1914 lines, 71527 bytes, 0 keywords
Compilation complete. 1 Errors, 0 Warnings, 0 Remarks, 0 Optimizations

This is the part of the code to be modified:
DefinitionBlock (
"acpi_dsdt.aml",	//Output filename
"DSDT",	//Signature
{
Scope(_PR_) {
   ...
So I fixed it adding the rest of the arguments for DefinitionBlock, but after 
rebooting and including the new aml file I get the same error if I get the 
dsdt table from acpidump. On the other hand, if I get the dsdt decompiling 
the file /proc/acpi/dsdt with iasl, I get these lines:
DefinitionBlock ("DSDT.aml", "DSDT", 1, "VIA", "PTL_ACPI", 100925440)
{
    Scope (_PR)
...
As this file compiles back without errors, I included DSDT.aml in initrd 
instead of acpi_dsdt.aml. Anyway it keeps giving the same results afterwards

These are the lines of dmesg with grep acpi:

If someone could give some light on this it would help very much, because I 
feel a little bit frustrated after dedicating so much time without results. I 
have recompiled different versions of the kernel a thousand times in these 
weeks with many different options. Now I'm working with 2.6.5 and apm, but 
the tests with acpi are with 2.6.4 after the acpi patch and another patch to 
use a customized dsdt -there is no patch available for 2.6.5-
If you need more information please tell me, because I am desperate to find 
some helping hand.
Thank you

when this happens, my empiric experience says that you should try ,
disable APIC in kernel configuration 
or 
boot with nolapic option ( that disable apic )

let me know the result of the test.

thanks,

Re: differences between acpidump and disassembling dsdt with iasl

[Emilio Mejía Fernández de Velasco]

When I compile the kernel to work with ACPI I choose not to include local
APIC. Otherwise it doesn't work at all.
In the kernel configuration with ACPI I leave blank the option
"Processor type and features ->
		[ ]Local APIC support on uniprocessors"

I get the same results with nolapic as boot option. The computer can only work 
for some minutes, and then it freezes.
This time I tried compiling with debug options in ACPI, but nothing relevant 
seems to be registered in /var/log/messages. Anyway here you can see the grep 
ACPI of this file:

And these last 4 lines repeat for 10 times, and then the computer freezes. It 
is completely blocked. It can only be rebooted with the power button. I have 
also tried to reach it from ssh, but no luck with this either.
The remaining of the messages file belong to the next boot.
There is another thing: I can make it go frozen faster, I just need to unplug 
and plug the AC adapter for a couple of times, and the I get the blocking 
again. -This only happens with acpi, not with apm-
I feel like throwing the laptop through the window.
