Re: [gentoo-laptop] Re: [gentoo-user] Problem with CPU temperature (Santa Rosa CPU)

[Marco Calviani]

Hi Beso,
   i have an Acer Aspire 5720. I've tried with the acer_acpi, it
compiles well but when it comes to loading it fails, saying
"No or unsupported WMI interface, unable to load".

However as far as i can understood, this module deals with issues of
buttons and hotkey not with ACPI issues.

Yes, my DSDT failed during recompiling, but i have managed to solve
the issues, and now it compiled well (with warning but i'm not
caring). I'll try to recompile the new DSDT in the kernel, maybe it
could help (but i'm not sure).

Regards,
m
