AW: Re: IBM Thinkpad A31 | ACPI problems

[Jörg Hänsel]

Dear Dom,
I have a Thinkpad R32 and the same problem (could not use EDCT). I hope that
IBM will release a new BIOS since ACPI does not work perfectly in Windows
2000 and XP as well.
(Meanwhile I am using APM instead.)
When I load the ospm modules (battery, etc.) there is no subdirectory acpi
under /proc but "battery" occurs directly under /proc and is empty.

Bye,
Jörg

Dear Sandro,

I posted the following message to the "Thinkpad A20,A21,A22,A30,A31" forum
at
IBM. Currently it looks like the posting has not been opened to public yet?
I
hope that IBM will provide a patch or that we can assist in creating a work
around for the buggy bios. I know several friends who are running Linux on
their A31's. Currently we all stick to kernel 2.4.19 + acpi-20020918 patch.
This combination provides at least some support for ACPI.

Thanks to the hard-working acpi-development team!
Dom

Hi all!

I am successfully running Gentoo Linux
(http://www.gentoo.org) on my new A31. Unfortunately
ACPI is not getting initialized properly with the new
acpi-patch from 20021212 ( + vanilla 2.4.20). I consulted
the acpi developers (http://acpi.sf.net) who told me that the
problem is the buggy BIOS! Is IBM aware of that problem
and are there any ongoing efforts to solve this problem?

Thanks!
Dom

Thanks Adachi, Kenichi for your immediate reply!

I browsed the mailing list archives (December 2002, November 2002) and 
encountered several postings from Sandro (PSI-Systems <psi-systems-8XqT/MH+8ao@public.gmane.org>) 
who is having the same problem with his Thinkpad A31 laptop: 
ACPI: Found ECDT
ACPI: Could not use ECDT
evxfevnt-0119 [06] Acpi_disable          : ACPI mode disabled

ACPI is completely disabled for IBM Thinkpad A31. Is there a solution for that 
problem available? How can I be of any help to the ACPI developers?

Thanks for any hints!

Dear Kenichi,

sorry - i did not see Andy Grover's reply to Sandro earlier on. So the problem 
is a bug in the BIOS implementation. I have already contacted IBM via "Ask an 
expert" and posted a message to http://www7.pc.ibm.com/~Thinkpad and I really 
hope that they will reply. I will keep you up to date.

Thanks,
Dominik

p.s. How ugly would a work around for the BIOS problem be? Aren't there 
already several work arounds for buggy BIOSes in the Linux kernel code?

Hi,

i'm also encountering the same problems with my (beloved ;) ) A31. So if there 
is a possible workaround - is anyone already working on it/how difficult 
would it be to implement such that hack?

Uh!
I didn't know that IBM has a forum. Where is your question located (I can't
find it)? Can you please email me if you find a solution for the whole prob?
I also questioned IBM about that prob a few days ago, but via support - no
answer so far.

Hello Dom,
Unfortunately, we do not have any information on whether or not the BIOS will 
be updated to resolve the issue you are having with the ACPI. This is up to 
the IBM Software Developers.
 
Thank you for choosing the IBM Forums.

Dear Mr. Bar,
you have contacted the technical support of IBM and we can't give you

Hmm ... if it turns out that IBM does not fix their BIOSes, I will have
to start advising people against buying Thinkpads. Period.

Perhaps we should find a way to make this very clear to IBM, and to
the other companies who think they will get away with not doing their
homework -- and of course to all potential buyers.

Nobody wants to give up their freedom, so the inability to run Linux on
a newly bought machine is something that will even annoy many of those
who are currently only interested in Windows.
