n00b!: help with kernel configuration

jeduars · n00b Joined: 12 Sep 2004 Posts: 3

hey, I have an IBM thinkpad t41(pentium m 1.5) and installation went reallly smooth however I can't seem to get the thing to shut down, after using the shutdown commands or shutting down form KDE the darn thing will not shut down... so i searched the forum and found that IBMs need to have local ACPI disabled in the kernel config....

supposedly i should disable with the make menuconfig thingy under the processor type and features category but the option

"[*] Local APIC support on uniprocessors "

[i'm using kernel 2.6.9-rc1-mm4]

is not there!!! so i kept searching the forums and found a patch for an IBM R51 that's supposed to fix the problem but i have no idea how to use the patch...

I tried using patch -p1 < /home/jed/disable-lapic-in-acpi-power-off-2.6.7.diff in the /usr/src/ directory but i didn't work... :roll:

Also the CPU throttling thing is all crazy, in the Klaptop thingy i set CPU throttling to 50% and it will work (sorta) then when i try to set the throttling to 0% the speed will stay at 50%!!! i think my power management is REALLY screwed........

could I have some help?! I've tried for two days and still can't get the thign to shutdown properly... guess i'm just too damn n00b

BTW the url for the "patch" is : http://onda.zvuk.net/r51/disable-lapic-in-acpi-power-off-2.6.7.diff

If you read the top part of the the patch you'll see the:

--- line
and
+++ line

The --- line is from the old non patched dir and the +++ is for the new dir.
So this patch looks specifically for a directory named (From the +++ lines):

linux-2.6.7/

So you need linux-2.6.7 to point to the kernel that you are building and that you intend to patch. Since you're running 2.6.9-rc1-mm4 and not 2.6.7 I recommend just putting a symlink in to trick the patch.

the official way is to change into the source dir and use p1 so:

cd /usr/src/linux; bzcat my_patch.bz2 | patch -p1

(I use the pipe thing cause its easier to adapt)

edit: Added list of decent cat commands
cat = general file
zcat = .gz file
bzcat = .bz2 file

I've the same Problem. I folloed your solution but my system again says "power down" and i have to press the powerbutton 3 seconds to shut down.
I installed ACPI and compilled it into the kernel (2.6)
Can you help me?

Linux will disable ACPI support completely if you are running a bios dated before 2000 (it usually makes this clear, check with "dmesg | grep -i acpi".
you can use the boot option acpi=force to force it to be enabled, but be careful..bioses from pre-2000 are generally quite broken ACPI-wise

My computer ist from 2002, so i dont think the bios-date is the problem

dsd · Posted: Thu Oct 14, 2004 9:13 pm Post subject:

but the bios you have installed might be from pre-2000...
go ahead and check the output of "dmesg | grep -i acpi" just in case..

i also get "power off" after executing "shutdown -h now". i don't know how moritzmahling solved his problem, and i tried following Khan's instructions with no success. what next?

I worked around with it and tried different settings. When you're in the Powermanagement Options (make menuconfig), I compiled "Power Management support" in the Kernel and used only "APM BIOS support" as module. Then it worked.
