Acpi Problem

Hello All,

I tried your latest acpi sources, using 2.4.20+patch and 2.5.50. But it does not work.
This is the acpi messages i have in dmesg:

Acpi is quite unusable. Is this a hardware problem? or is my machine not yet supported?

Thanks in advance for your response.

Hello All,

It seems my problem come from a bad bios from IBM..
And because acpi work under windows, they doesn't release a new version correcting my problem (Could not found ECDT).
So if i understand it is a fault from IBM, no?
perharps it is a stupid question, but for curiosity, what is the difference between the windows acpi implementation and yours?
which i could perhaps respond myself that we don't know how microsoft have done it because it is closed source... but i wish someone know something more on this.

If we cannot do somethink without a new bios from IBM, i think that i will contact them for asking them to do something.. i bought a computer, the minimum is to have it working with the standards.. the more we will ask for this new bios, the more chance we have getting one ;).
But i do not know what to say about the technical side.. could someone help me in saying what is the real problem?

Thanks in advance, :)

Tom
