Hi Oisin,

since I've compiled my DSDT yesterday and load successfully, I tell You, that with 2.6.8.1 there is an option in the kernel to load an custom dsdt, where have to tell exactly( full path), where the dsdt is and it was loaded successfully.

Maybe that helps You.

Regards

Hi all, sorry to bring more mundanity to the list, but this has been really annoying me for the last day or two.

I (probably) fixed my DSDT, compiled it successfully, and have tried numerous ways of loading it at boot through an initrd patch (I couldn't find a 2.6.8 patch, but the 2.6.7 patch I found seemed to apply well enough, without much fuzzing...).
The machine appears to find it, but it doesn't actually load it. If anyone knows why not, or if I did something obviously wrong, please let me know.

thanks,
Oisín

here's the relevant output in dmesg - I believe if it had loaded the tables from the custom DSDT, it would have said so just after the "ACPI: Subsystem revision nnnn" line (and I can tell that it hasn't, as it refers to an error in the DSDT I had fixed, by changing both references to Z00D to Z00C):
