HOWTO Fix A Buggy DSDT File

[67GTA]

I only got as far as the fourth step

iasl -tc /home/<yourusername>/dsdt.dsl

Afterwards, this is what came up.

/home/adminwalter/dsdt.dsl     1: [*** iASL: Read error on source code temp file /home/adminwalter/dsdt.src ***]
Error    4095 -                  ^ syntax error, unexpected $end, expecting PARSEOP_DEFINITIONBLOCK

Error    4010 - Could not close file "/home/adminwalter/dsdt.hex" (No space left on device)

Segmentation fault

I'm not sure how to proceed from here.

From the error message, it looks like you have some text that shouldn't be there at the top of the file. I would have to look at it. Zip up a copy of the original dsdt.dsl file and attach it here.

Here it is. Sorry that I didn't zip and upload the file through Ubuntu, but Just recently, I couldn't open Firefox at all on Ubuntu.

Hi 67GTA, would you mind helping me with this dsl file?

$ iasl -tc dsdt.dsl

It's a Toshiba U400-130 and I reckon that it runs a little hot. Otherwise, everything seems to be working though...

I think I'm screwed!

Here's the output when trying to re-compile my unchanged DSDT:

Here's the DSDT:

Where do I even start!?

That may or may not be too bad. One small error can throw everything into a tailspin. The compiler gives up after 200 errors. Zip up a copy of your dsdt.dsl file and attach it here. I will take a look at it.

Here it is. Thank You!

This will probably not work with the 2.6.31 kernel. I don't think the custom dsdt patch has been compiled in to it yet. 2.6.28 is the latest version (Jaunty) I'm sure it will work with. All of the custom patches like this aren't included until the final release.

I won't be using .31 since I got some segfaults on the logs.

As you suggest I found the line referring to the custom DSDT.
Here's the ACPI messages from dmesg: http://paste.pocoo.org/show/133255/

Thank You! However, temperatures are the same they were before I tried the .31 kernel. Still too high.

Do you have a link to the laptop product page? I was trying to run down the specs, but LG doesn't list laptops on their site.
