Acer Extensa 3002 WLMi: Help wanted fixing the DSDT

[Berthold Cogel]

Hello!

I've exported the DSTD of my notebook (Acer Extensa 3002 WLMi) and tried
to recompile it:

Then I patched the DSDT with the code from the sbs-linux project
(sbs-cm-20050328, acer-tm4xxx-sbs-cm.diff). Recompiling gives some
errors I haven't fixed yet:

Does anybody know how to fix the DSDT?

Thanks,

With this Version I have had no chance to recompile my DSDT. When I try to 
load the changed DSDT my machine reboots immediytely - the produced code 
seems to be incorrect. Try version 20041203 (or newer)

Regards and good Luck
	Olaf

BTW: If you want to you may get my patched DSDT - I've got the battery thing 
working. You may mail me if you are interested in this.

Hello Olaf,

thanks a lot for the offer. Of course I'm interested.

At the moment I have a working 2.6.11.11 kernel with the SBS driver from
Rich Townsend and suspend2. But I'd like to use a more recent kernel. So
I have to get the DSDT working.

I've tried to compile newer versions of iasl on my system (Debian
stable), but it always ended with some errors so far. So I got me a
prebuild version 20040715 from the web, I found somewhere.

I had the reboot problem myself with the fixed version of my original
DSDT (without sbs patch). It has something to do with the thermal
management.
I got a lot of messages about increasing temperature in the logs and the
system has shut itself down more or less immedeatly.
The system had to cool down a bit, before I tried to test a new kernel.
After this, the system was stable after reboot.

I've tested my patched DSDT, although I got the error messages from the
compiler (Just curiosity ...). With the sbs patch, the battery readout
was working for some time. But after about 30 minutes the battery state
wasn't available anymore.


Best regards,

Berthold

hi!
I heard the extensa 3002 doesn't differ a lot from travelmate 4001(which is 
mine). my laptop works ok. it WORKS. but i've got a few problems:
	1, i tried modifying my DSDT with sbs-linux's patch, the compile error 									    
disappeared, but the battery reading wouldn't work. so i'm stuck with 
i2c-acpi-ec, which works fine, but needs some modification in newer kernels.
	2, speedstep isn't recognised, though i've got centrino in here (I heard this 
is because of incomplete BIOS acpi implementation), can this be fixed by 
fixing DSDT?

Hi Berthold,

I'll send it to you by mail. ( anyone else? :-) )

With the kernel < 2.6.12 i used the acpi-ec-nospinlock patch included in Richs 
sbs-package. Later i had to use the ec-burst patch from Luming Yu from here:

http://bugzilla.kernel.org/attachment.cgi?id=5574&action=view

Then I have to pass ec_burst=1 as kernel parameter. Without this my machine 
misses keystrokes when I'm typing "fast". (I use this with a 2.6.13 vanilla 
kernel)

Perhaps this has to do with the flex version on you machine. I've read about 
some problems due to a too recent version of this package. I'm using gentoo 
so I'm not sure, but there seems to be a flex-old (or something like that) 
for debian with which you may have more luck getting iasl compiled.

Yes but this even happens if you recompile a "unchanged" DSDT. So the produced 
code is not usable I'm afraid.

I'm using my patched dsdt since february this year and the battery status is 
working without any problems on different kernel versions. The only issue i 
had was the missing keystroke problem. BTW. I'm using the acpi-dsdt-initrd 
patch for "feeding" my dsdt to the kernel.
