I would like to know which modules do i need to pass with mkinitrd if
the root partition of my linux is XFS.
normally mkinitrd knows which it has to take when the filesystem is
specified with -f option.
the command i used is the following:
#mkinitrd -c -k 2.6.24.5-smp -m xfs -f xfs -r /dev/hda1
but at load of linux it fails when mounting root.
i think that's because i didn't specify all modules needed at mkinird.

Which version of Slackware?
You don't need to use mkinitrd any longer if you want to use XFS.

slackware 12.1
with kernel 2.6.24.5-smp

??
why?
linux actually uses a module called xfs when an xfs partition is
present.

My bad, it turns out that I by old habit has chosen the huge-smp kernel
and this kernel has build-in support for XFS so no ramdisk is needed.

Not if its compiled into the kernel. I'm a bit rusty here but I has used
a ramdisk to load XFS support but its years ago but I think it was
something like:
mkinitrd -m xfs
Or maybe:
mkinitrd -m exportfs:xfs

That looks right to me. I tested a similar initrd on a system that I
use which is using XFS as root and it worked without a hitch. I was
testing under Slackware 12.0, which AFAIK is very similar to 12.1.
I checked the modules.dep file, and AFAICT xfs has no other dependancies.[color=blue]

Fails how? With a kernel panic?[color=blue]

Note: two comments inline.
The bootup messages scroll by pretty fast, but did you see a message
saying that XFS is loaded? If not, then there is something wrong with
either your initrd or the parameters given to your bootloader.
In general terms, there are various things that can be broken:
1. You may need a module for your specific disk controller device. This
shouldn't be the case for common IDE and SATA controllers.
2. You may have neglected to fixup your bootloader completely and correctly.
If your bootloader has missing information, then it can't be expected to
guess. Note: lilo requires more fixups when making these changes
than grub. Which bootloader are you using?
3. It could be something else. Check the directory /boot/initrd-tree to see if
anything is out of the ordinary. Check the file, load_kernel_modules, etc.
You can always manually make corrections and rebuild from this tree using
cpio directly:
(cd /boot/initrd-tree && find . | cpio -o -H newc | gzip -c) >/boot/initrd.gz

alright, there was nothing wrong here.
i did it again and it worked straight forward.
I might have done something wrong. but i don't know what.
