[Solved] mkinitcpio not generating correct image

First of all, I have two partitions running Arch, one being experimental for messing around. You might have guessed that I wanted to ask something about screwing up my experimental Arch, but sadly it's the other one that's not working. sad

I'm running both Archs with kernel26-2.6.20. So this is what happened, in the stable Arch, if I run mkinitcpio with verbose output, I see modules being added to filesystems hook, but nothing too other hooks. If I do the same thing in my experimental partition, I see modules added to ide/sata/filesystems. Both Archs have same mkinitcpio.conf.

How did this happen? I guess it happened roughly a month ago while I was upgrading the system, and it was upgrading kernel/mkinitcpio/<whatever is related> I cant remember exactly which package was being upgraded. I accidentally cancelled the upgrade. Then I just reinstalled whatever package I cancelled thinking all is still fine. After a reboot kernel complained that root could not be mounted. Then I realised there's something wrong with kernel26.img.

I then use my experimental Arch to generate kernel26.img and then both Archs worked fine again. However I still can't generate a proper kernel26.img in stable Arch. The incorrect file size for kernel26.img is ~650KB and the correct one is ~900KB.

If anyone knows what could possibly screw hardware detection up when doing mkinitcpio, please help me.

Thanks a lot.

Re: [Solved] mkinitcpio not generating correct image

Are you possibly running under a different kernel than you're building for?  For that you'd want the -k parameter.  However, the presets should handle this case well - that is, try running "mkinitcpio -p kernel26" to build the preset kernel26 images.

Re: [Solved] mkinitcpio not generating correct image

Thanks for the reply.

I'm very sure the two kernel versions are exactly the same, but I've tried again with mkinicpio -p kernel26 anyway, it still produces a ~650KB kernel26.img compared to ~900KB from the experimental Arch. But I think the problem is less relevant to kernel version as doesn't matter which kernel I choose to install, it'll always produce an incorrect kernel26.img.

I've been trying for a long time to find out what exactly the differences between the two Archs are that caused the problem. Like I mentioned, no modules are being added to ide and sata hook, I'd really like to find out what caused it and how to fix it. I've already tried reinstalling mkinitcpio and gen-init-cpio, I'm not sure if there's any other package I should try reinstall.

Thanks a lot

Re: [Solved] mkinitcpio not generating correct image

Ya know, I've seen this crop up with a bad module at one point... a module installed into /lib/modules/<kernel version> that is invalid for that kernel version... did you do something like that?

Re: [Solved] mkinitcpio not generating correct image

As an experiment, I did this

cd /lib
mv modules modules.bak && mkdir modules && pacman -S kernel26

Incorrect kernel26.img is still being produced....

I'm not sure if reinstallation is the only option left.

Re: [Solved] mkinitcpio not generating correct image

Ok, one thing to try:
Can you check exactly which modules the "stable" arch uses and add those directly in the MODULES="" setting in mkinitcpio.conf?

Also, what did you do that makes your "experimental" arch "experimental"?

There's nothing in MODULES section in mkinitcpio.conf (both stable and experimental are the same).

My experimental Arch is just for installing whatever I want to try out first before installing on my stable Arch, but however it still uses the "current" repository. Things I try out like Beryl etc.

Here's what it looks like when generating kernel26.img on the stable Arch:

Re: [Solved] mkinitcpio not generating correct image

Can you "ls -l /lib/modules/2.6.20-ARCH/kernel/drivers/ide" in the experimental one?

Also, could you try running "depmod -ae" and trying to build again?

Tried depmod -ae, still the same, nothing under ide and sata hook.
I'm currently looking at mkinitcpio scripts, so far I've found out in /lib/initcpio/install/autodetect, the content generated in /tmp/initcpio_modules.XXXXXX from autodetect is shorter in stable Arch than the experimental Arch. I'm still investigating why.

Re: [Solved] mkinitcpio not generating correct image

Ok I've found out a bit more now, in /lib/initcpio/functions auto_modules()

On this line

modprobe --set-version ${KERNELVERSION} --show-depends -a \
        $aliases

This line produces nothing on the stable Arch, but produces a list of files in the experimental Arch. Hope this can help you determine where the problem lies.



Update:
I've discovered this, when manually running

modprobe --set-version 2.6.20-ARCH --show-depends -a pci:v00001022d00001103sv00000000sd00000000bc06sc00i00

where that pci id is picked from the first line in $aliases, on the experimental Arch it produces 

insmod /lib/modules/2.6.20-ARCH/kernel/drivers/hwmon/k8temp.ko

However on the stable Arch this is produced

Usage: modprobe [-v] [-V] [-C config-file] [-i] [-q] [-b] <modname> [parameters...]

Now the question is why is this happening?

Re: [Solved] mkinitcpio not generating correct image

Reinstall module-init-tools. I believe I know what happened to your system, but first see if that gets you a working image.

Thank you all very very very much!

But I'm not sure why modprobe are in two places, /bin and /sbin ....

Steady on... smile You may still have other problems.

modprobe is in two places because you decompressed kernel26.img into your running system at some point during your investigation. Is that correct? If so, you may have replaced other binaries as well. Use this entry:

gzip -dc < /boot/kernel26.img | cpio -t

to list all the files in the image, and check them against the correct versions.

Ah good call... yeah cpio images are a bit daft.  Unpacking them can and will extract right over your / directory.
That's kinda why I renamed the cpio.gz files to "img", to prevent people from trying to inspect them and doing something like this 8)
