Can't get ACPI to work on a Panasonic Toughbook CF-52

Quoted 5 lines · Ralf Orlowski

Hello,

sure, that is no problem.

Bye Ralf

Thanks for the info.
That the system can't be booted in ACPI mode is caused by the broken bios. And the bug is caused by the following definition:

Quoted 2 lines

Name (ASLB, 0x00) (It is defined in the scope of GFX0 device) OperationRegion (IGDM, SystemMemory, ASLB, 0x2000)

The correct definition should be the following:
OperationRegion (IGDM, SystemMemory, \ASLB, 0x2000)

Now there is another similar bug in the kernel bugzilla.
http://bugzilla.kernel.org/show_bug.cgi?id=9915

Will you please try the custom dsdt and see whether the system can be booted with acpi enabled?
How to use the custom DSDT can be found in http://www.lesswatts.org/projects/acpi/faq.php.

Thanks.

Will you please try to boot the system with the option of "acpi=off" and attach the output of acpidump, lspci -vxxx ? Thanks.

Hello,

I just got a new Panasonic Toughbook CF-52. I installed the system with debian sid and except of the ACPI-Support the system runs fine under linux. But so far I had no success to get ACPI working on the system.

Today I installed kernel version 2.6.25-rc9 on the system, because I
read, there should be a patch included, that make ACPI work on my
system. But so far it does not.

The kernel runs fine with ACPI disabled, but with ACPI enabled the boot just stops with a message about ACPI interrupts.

Does anyone know, what I could try, to get ACPI working, or how I could find out more about the problem to may be help to find a solution?

Bye

Ralf

I just tried the DSDT I downloaded from
http://bugzilla.kernel.org/show_bug.cgi?id=9915

Now it gets a little bit further when booting with ACPI enabled, but at the end it still hangs. :-(

I get several messages "Could not map memory", "AE_NO_MEMORY" and "Method parse/execution failed". And then the boot stops.

Is there a way to write these messages somewhere before the system stops, so that I could post the exact messages here?

But so far I'm still not able to start the system with ACPI enabled. :-(

Will you please attach the output of acpidump.out and send it to me? I'd like to help you.

Of course you can do it by yourself. (First you should install iasl compiler) iasl compiler can be downloaded from :
http://www.acpica.org/downloads/index.php

#acpidump > acpidump.out #acpixtract -a acpidump.out ( You can get the DSDT.dat) #iasl -d DSDT.dat (Get the DSDT.dsl) #modify the DSDT.dsl #iasl -tc DSDT.dat More detailed info can be found in In
http://www.lesswatts.org/projects/acpi/faq.php Thanks .

Thank you very much for your help. That hint brought me a big step forward. This way I managed to change the DSDT and compiled it into the kernel.

So now I can boot the system with ACPI enabled.

Now there's only one problem left:
I can send the system into suspend mode now with the power button or if I close the display.
But when I try to wake up the system from suspend mode it looks likes it wants to start up, but the display stays dark and it seems that it is hanging somewhere within the wake up process. I can't even blindly change to a text console and type a reboot there to restart the system.

So are there any hints, where I can look for a configuration option to make this work also?

Bye Ralf

P.S. should I post something about the solution for starting the CF-52 with ACPI enabled somewhere, so that this may also help others?

Sorry that you can't use the custom DSDT downloaded from the bug9915. You had better modify the DSDT based on your laptop.
To modify the following will be OK

OperationRegion (IGDM, SystemMemory, ASLB, 0x2000) // This is incorrect. The correct definition should be the following:

    OperationRegion (IGDM, SystemMemory, \ASLB, 0x2000)
