IBM Thinkpad A31 | ACPI problems

[Dom]

Hi!

I have got a IBM Thinkpad A31 notebook (BIOS Version 1.04, 
http://www.pc.ibm.com/support?lang=en_US&doctype=&subtype=All&page=brand&up=unknownuser1004106089&menu=model&brand=IBM+ThinkPad&family=IBM+ThinkPad%7CThinkPad+A31&machineType=IBM+ThinkPad%7CThinkPad+A31%7C2652&model=IBM+ThinkPad%7CThinkPad+A31%7C2652%7CM5G) 
which is running Gentoo Linux 1.4_rc1. The previous gentoo-kernel based on 
2.4.19 with acpi-20020918 is running quite smoothley except for some problems 
with the battery state:
 
---- fragment of /var/log/messages: 2.4.19 + acpi20020918 + gentoo patches

Now I compiled a new kernel 2.4.20 with the acpi kernel patch-20021212 and 
ACPI does not work anymore. :-( 
"ACPI: Found ECDT
ACPI: Could not use ECDT"
How comes? If it is of any help to you I would provide further information 
(log messages, etc.) regarding this issue. Thanks in advance for any help!

It must be (well) known, but I don't have precise information. Please
check out the ML archive for ECDT support status in the latest code. You
can surely find out the right answer with full description.

# FWIW, any version of Windows aren't yet __fully__ ACPI 2.0 compatible
so far, and they simply ignore ECDT if present.

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!

IBM Thinkpad A31 | ACPI problems

[Dom]

Dear Hubert!

According to the Linux ACPI developers the IBM Thinkpad A31 has a buggy BIOS. 
Recently I have heard/read rumors that SuSE is cooperating with IBM 
concercing the ACPI implementation of Thinkpad notebooks. There seem to be 
many Thinkpad owners having the same problem with ACPI support. 
Today I have tested your SuSE kernel (suse-2.4.19-41 [20030103]) hoping that 
ACPI might work. ;-) Could you please inform us what the status of the 
cooperation with IBM at SuSE is? Are there any efforts at IBM to fix the 
buggy BIOS or at SuSE to implement a work around for the buggy bios? Any 
information is highly appreciated!

Best Regards,
Dom
