HOWTO Fix A Buggy DSDT File

[calimancer]

Hi 67GTA!

I read in that you can do magic with DSDT.
I need your help. I have these four errors and don´t know how to fix them:


/home/cali/DSDT.dsl 9164: Alias (^AGP.VGA.UDCS, UDSC)
Error 4064 - Object not found or not accessible from scope ^ (UDSC)

/home/cali/DSDT.dsl 9165: Alias (^AGP.VGA.LCD, PLCD)
Error 4064 - ^ Object not found or not accessible from scope (PLCD)

/home/cali/DSDT.dsl 9166: Alias (^PB2.VGA.UDCS, UDS1)
Error 4064 - Object not found or not accessible from scope ^ (UDS1)

/home/cali/DSDT.dsl 9167: Alias (^PB2.VGA.LCD, PLC1)
Error 4064 - ^ Object not found or not accessible from scope (PLC1)



My laptop is a Toshiba L505D-S5992.
Here is my dsdt.dsl file:

Thanks 67GTA!!!
Now, I'm going to try it.
Why Toshiba has this kind of problems if they are one of the precursors of ACPI?

Most of the time, the hardware vendors use the Microsoft compiler to recompile the DSDT against their hardware. The PC manufacturers as a whole usually are not aware of the difference between MSFT and IASL, just developers and programmers.

I just tried fixing this under an updated 9.10 installation before I saw the warning on the OP... Is there no longer a way to fix it by myself?

BTW, where should I file a bug report?

[67GTA]

The only way is to compile your own kernel with the DSDT patch included. I wouldn't recommend this method. You need to register and file a bug on launchpad.

Hello Friends,

hi ;D

obviously, i also have a problem with dsdt... so, here partial dmesg:

[ 18.962087] ACPI Error (psargs-0359): [^CKDY] Namespace lookup failure, AE_NOT_FOUND
[ 18.962100] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.BASM] (Node ffff880037a653b0), AE_NOT_FOUND

hardware is:

fujitsu-siemens v6555, core2duo t5870, chipset nvidia mcp79 - buyed without os (;D)

i suppose this dsdt is not working correctly, because fans not work at all; here the output by sensors (by thermal and coretemp modules):

finally, i tried to fix dsdt, but i'm not so able ;D - here first output:

i tried to search for some fix about "4095 error" and i found that is first row to delete:
first row in dsdt.dsl is
"ACPI Error: ACPI path has too many parent prefixes (^) - reached beyond root node 20090521 nsaccess-526"

and finally, if i delete this row and try to recompile with -tc, i have 201 errors ;D


ok, i have to stop ;D



in attach, there are dsdt.dat (same /proc/acpi/dsdt), dsdt.dsl and dsdt.hex


ah! searching for "linux + fujitsu amilo v6555" in google... obtain 0 (ZERO) results ;D
too, too young :/


pardon for my english, but i'm italian

p.s.: i'm using debian (testing) - i think it's not so different fro *ubuntu, but in doubt i preferred to specify

thanks in advance,

Perhaps my search terms aren't exacting enough when trying to find an explanation for any of the 7 warning messages listed above. I apologize if it has already been mentioned under this topic.

In closing, I am kindly requesting anyone's assistance in trying to resolve or remove the error/warning messages listed above.

I am not sure if it matters, but the attached dsdt.dsl is from an ASUS P5Q.

Thank you very much for your time!


Best regards,

IanT


PS. Is it best practice to extract dsdt from an original, unmodified, bios? The reason why I ask this, especially as a post-script message, is because I wonder if some of my problems are attributed to a modified bios, and hence dsdt might have been altered somehow...?
