    Can you please help fix the above errors so I can compile and use it on my Ubuntu 11.04 installation?

    I have attached the DSDT file for easy reference.

    Thank you.
    Fixed. Should have Provided me with the .aml instead.

    Re: HOWTO Fix A Buggy DSDT File

    finished... (par one bug, which i found info on here), but i'll just leave that one as i don't think it'll affect anything much...

    attached is my final dsdt... maybe it will be helpful for anyone with hp g6 to diff... if anyone can give the start to finish a quick diff to check my changes would be appreciated...

    cheers,
    mike

    Re: HOWTO Fix A Buggy DSDT File

    Hi,

    Could someone help me fix my DSDT table ? I'm stuck with the warning and remarks, I've fixed the 2 errors (Min/Max error using Max - Min + 1 equation).
    I've got an Acer 4820TG with 1.25 bios, maybe someone as already fixed the dsdt table.
    Particularities of this model : ATI switchable graphic between Intel GPU and ATI GPU.
    System : ArchLinux.

    I've attached my dsdt.aml (and .dsl if you need it) to the post.

    Thx,
    Qiou.
