I suspect the manufacturers would say "Oh, the sensors?  The BIOS

isn't broken, you're just supposed to use WMI or some (undocumented)

ACPI device to get at those."


I know next to nothing about WMI, and there are probably IP issues

in that area.  But I'd rather spend effort in figuring out the "right"

way to do this.  Until we do it the same way as Windows, we can pile

on hacks till the cows come home, and we'll still have issues.


I added Carlos to the cc: list because he's been doing a lot of


Windows apparently doesn't reject those resource declarations, so I'm

a bit hesitant to do it in Linux.  That tends to cover up problems,

and then it becomes very difficult to remove the band-aid and figure

out a correct fix in the future.

It's quite possible - can we have DSDTs for the boards in question so we can

quickly check if this is a possibility? (Basically, to see if they have

PNP0C14 devices - if they don't, then I'm afraid it's nothing to do with

WMI).

Hi Carlos,


I've attached the DSDT for Gigabyte GA-965G-DS3 (rev 1.0, bios rev. F9) to

bugzilla entry #9514:


http://bugzilla.kernel.org/attachment.cgi?id=14132


Thanks,

A quick look over the DSDT shows that there is no ACPI-WMI mapper device

(PNP0C14) on this board; so WMI is, at least in this case, not the solution

to this bug.
