I get up this morning and try to reboot the computer with ACPI enabled, and I still get the same crap!!!!!! Even after recompiling the kernel with ACPI support, it still says "acipd: failed, cant find /proc/acpi/events" What good did it do me to compile the kernel if it still doesnt work?

EDIT: other people have gotten it to work on machines similiar to mine, so I dont understand what the problem is here

Uh... maybe you did something wrong.

Sorry, you give no details.

I patched the kernel with the proper patch from the acpi website using kernel 2.4.21-013mdk. I cd to the linux drectory, did "make mrproper" then I did "make xconfig" which brought up the kernel configuration tool. I selected the ACPI options i wanted, as well as changed my processor to the proper thing, also disabled APIC as well as all of the APM stuff. Then i did "make dep" followed by "make clean" followed by "make bzImage". Then I did "make modules" which took on the order of about 6 hours. Once that was done I did "make modules_install" and then "make install". Did I miss something here, and how do I know I booted onto my new kernel instead of my old one? My ACPI still has yet to run Any other info you might need, let me know

You're going to need to edit /etc/lilo.conf and run LILO (or do grub stuff for grub) to switch kernels. Add an entry that's a duplicate of your current but with the new kernel's name in place of the old.

And copy it to /boot.

Do 'uname -a' to find out what you're running.

Or maybe my head's up my ass. Maybe make install should have taken care of all that? It's been a long time since I compiled a new kernel and it was on Core. I just remember copying crap and editing crap by hand. Sorry - I posted too quick before my brain caught up.

I ran LILO from the terminal, and I guess that replaced it, but now since it has ACPI enabled, it wont boot. I dont get it

Hm. That sucks. I don't know anything about that part of it. You might need to install acpid, maybe edit a config script to start it, maybe edit /etc/acpi/events so that there'd be something in /proc/acpi/events. I don't really know. Try something along those lines? Good luck.

I have acpid installed, but its like it points to the wrong directory. Any ideas on how to change it? You cant write to the /proc directory since its read only. It has to be started with that in there

I decided to upgrade to the 2.4.22 kernel, only this is the trouble Im having. Can anyone help me with this?

Not sure about the acpi stuff but, on that link, you could open an xterm and do 'make menuconfig'. (I think that's it.) And then there's 'make config' which, I believe gives you a whomping big file to edit. I've only ever used the TUI in console but I'm actually looking forward to trying xconfig.

are you 100% positive that all you changed was the ACPI options?

Just asking because I remember recompiling with ACPI support built in, and finished up going through the entire kernel and removing some things I should have left in ... and yeah, nothing happened when I booted up :-)

if you did remove other options, try finding an older configuration file of a kernel that worked when you recompiled it, and only adapt the ACPI features. If it still doesn't boot then, I'm dazzled

if you didn't play with other options, I'm just as well dazzled I'd say to compile them in as modules, but that can't make a difference to wether it boots or not, I guess...

After you finish compiling, there's a few more steps to go to make your computer boot from the new kernel. You have to copy the new kernel and the new System.map, to your /boot directory, then create a new 'initrd.img' file there. Then you re-configure /etc/lilo.conf and run 'lilo'.

To make the new 'initrd.img' file, type the commands:

cd /usr/src/linux
mkinitrd ./initrd-2.4.21-0.25mdkcustom.img 2.4.21-0.25mdkcustom

Don't miss the period after the 'mkinitrd' command. This command takes the form:

mkinitrd ./<kernel_version>.img <kernel_version>

The example above shows that you use whatever name you gave your new kernel; in my case it was '2.4.21-0.25mdkcustom'.

In /usr/src/linux you will find a file called 'System.map'. It's a good idea to make a copy of this as System.map-<kernel_version> in /usr/src/linux.

Rename 'vmlinuz', 'initrd.img' and 'System.map' in /boot to 'vmlinuz-old', 'initrd.img-old' and 'System.map-old'. Now copy the new versions of these files into /boot. These steps are completed by:

cp /boot/vmlinuz /boot/vmlinuz-old
cp /boot/intird.img /boot/intird.img-old
cp /boot/System.map /boot/System.map-old
cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz
cp /usr/src/linux/initrd-<kernel_version>.img /boot/initrd.img
cp /usr/src/linux/System.map /boot/System.map

Make a copy of your /etc/lilo.conf as lilo.back, then change your lilo.conf to make it look like this:

#---------start of /etc/lilo.conf---------------

boot=/dev/hda
default="linux"
prompt
timeout=200
vga=788

image=/boot/vmlinuz
label="linux"
root=/dev/hda1
append="devfs=mount hdc=ide-scsi acpi=off quiet"
read-only

image=/boot/vmlinuz-old
label="linux-old"
root=/dev/hda1
append="devfs=mount hdc=ide-scsi acpi=off quiet"
read-only

image=/boot/vmlinuz
label="linux-nonfb"
root=/dev/hda1
append="devfs=mount hdc=ide-scsi acpi=off"
read-only

image=/boot/vmlinuz
label="failsafe"
root=/dev/hda1
append="devfs=nomount hdc=ide-scsi acpi=off failsafe"
read-only

other=/dev/fd0
label="floppy"
unsafe

#----------------end of lilo.conf------------------

In this example, the section in bold has been added. You do this by copying the first 'image=' block of your lilo.conf and pasting it directly below, then changing the names in the first two lines to add the '-old' suffix. [I'll clarify this: the idea is not to make your lilo.conf look like the above example; rather, it is to take whatever yours is, and modify it by copying the first block, pasting it underneath with the '-old' names.]

When that is done, type:

lilo

You should now be able to re-boot your computer and be able to select between your new and old kernels.

I changed all of the ACPI options from "m" to "y", all of the ones I needed at least. It boots now, but ACPI still fails to start, giving the same error message as before "starting acpid: failed, cant open proc/acpi/events"

what is your chipset version?Sometimes there are special requirement for kernel compiling. As for my experience,nvidia-nforce2,I should disable the 'acpi' in the chipset bios option before I compile the new kernel.

As far as chipset, Id have to look when I got home (fall break :-D). By chipset you mean motherboard, right? Anything else you want to know, I can probably tell you. Im just somewhat stumped as to why it still doesnt work. I think geoff_f may have found part of the problem, in that Im still booting onto the old kernel. Im going to try what he suggested later on this afternoon.

Um, just a guess here, but "acpi=off' on as kernel options in lilo.conf may need to be
'acpi=on'...

Just a stab in the dark
