ACPI and my IBM Thinkpad R32

ACPI and my IBM Thinkpad R32

[Michael Wahlbrink]

Hi,
here comes an ACPI-Newbie with some (perhaps stupid) questions ;-)
I've got an IBM Thinkpad R32 (Type 2658-DCG) and tried to get linux working on it. Ok all is set up excl. powersave etc.. (the ACPI) stuff. I've tried a vanilla 2.4.19 kernel enabled acpi and got some informations about battery temperature etc in /proc/acpi/ . Then I've read an article about linux and ACPI in the german ct'.  ...And so I've found this project... Ok, I patched a 2.4.20 and a 2.4.21-pre3 kernel with the ACPI-patches from sf. Now I got no readable Information in /proc .. :-( Now I get the following messages about acpi when booting up (kernel 2.4.12-pre3 with patch):

Linux version 2.4.21-pre3-acpi (root@flat-eric) (gcc version 2.95.4 20011002 (Debian prerelease)) #2 Thu Feb 13 16:29:32 CET 2003

Hm, what's going wrong here, whats to do to get it fixed (2.5.xx or a newer patch or another config??). If you need more configuration details, please ask. I can also test some other configurations or versions (its at the moment a test mashine). So thank you for reading this mail ;-) and hopefully answering some newbiequestions....

regards
micha

ct' wrote an article on Linux and ACPI?

Anyone have a URL?

Michael - ACPI is being disabled because of a known ECDT BIOS bug. IBM
has promised to fix this in a forthcoming BIOS update.

There is a little problem in this laptop.
IBM will release soon a bios upgrade.

In the meantime, you can check

for a workaround.

It seems to be not availabe online - at least thats what a quick search 
said
(http://www.heise-online.de/ct/inhverz/search.shtml?T=acpi&Suchen=suche)
On the other hand, since the article is obviously co-authored by Dominik
, he might be able to send you an electronic version. 

Otherwise I would offer to write a short sum-up (or answer certain
questions) - in case I did not yet threw away the respective issue.
