[ACPI-sppt] ACPI Issues with IBM Thinkpad X.31 (pentium M + ICH 4)

Hi all,
(Please CC me any answer, I am not subscribed to the list, thanks)


I'm quite a newbie with ACPI, so please forgive me if this is a FAQ. I
have an IBM Thinkpad X.31 with the BIOS Upgraded to the latest version.
I'm using kernel
2.6.0-mm1 with latest acpi patches (although I've seen the same errors
with previous versions as well). The laptop boots fine, but the /proc/acpi
entries are almost unusable (no BAT, no THM), and I got some errors
regarding the Embedded Controller. I'd be grateful if you could give some
some pointers or comments....


What I have done:

* Make sure I have the latest ACPI patches.

* Make sure that the BIOS passes the blacklist :)

* Checked the acpi.sf.net db to see if there are DSDT tables for my model

* Checked that this model does not have the ECDT bug found in previous
Thinkpad models.

* Try to fix the DSDT table myself. dumped the DSDT table, compiled it (5
errors, 2 warnings): My understanding of IASL is null, but following some
docs, I added default return statements (not all paths return xxx),
commented some strings "Windows 2000" and Changed some OperationRegion
values (mostly increasing the last parameter by 1).  Compiles 0 err 0
warn. Patched osl.c with new table (AmlCode).... Boots fine, I see
something like "OS overrides table", but still the same errors.


* Look at the acpi.sf.net mailing lists.
(No matches found for AE_TIME) :~ weird...
(No matches found for X.31)

* (Desperate): since errors are mostly AE_TIME, I increased the default
DELAY for EC operations from 10 ms to 100 ms. Nothing :)


You'll see the errors later in this mail.


I honestly don't know what else to do. I understand that the ACPI
subsystem is a work in progress, so are those messages related to missing
features?  I'd really appreciate some pointers.


Thanks in advance,

Regards,
Ramon

The output of dmesg is the following (this version is without the
os_table_override patch, but the errors are the same):
