2.4.21 doesn't boot: /bin/insmod.old: file not found

2.4.21 doesn't boot: /bin/insmod.old: file not found

[Ronald Bultje]

Hey,

I'm trying to get 2.4.21 to run (2.4.20 runs nicely), and I get the
above error ("/bin/insmod.old: file not found"), after which it stops
booting.

After that, I installed the newest modutils (2.4.25) and
module-init-tools (tried both 0.9.12 and 0.9.13-pre), created symlinks
in /bin for all *mod* tools pointing to /sbin/$file, and I still cannot
get 2.4.21 to get further than this error (obviously, /bin/insmod.old
_is there_, I'm not that stupid. ;) ). I use initrd with filesystem
modules and some more in it, so obviously it fails with a panic saying
that /sbin/init wasn't found (no single HD mounted).

Of course, I could place ext3 in-kernel, but that's not the point.
2.4.21 doesn't boot for me as is - 2.4.20 does. I can't continue 2.5.x
testing if I remove the module-init-tools and only use modutils (I'm
doing that on another system, and that one works well with 2.4.21).

Does this sound familiar to anyone? Does someone know a solution that
will allow me to keep on using initrd images in 2.4.x, while also being
able to test 2.5.x?

System: RH73 (mostly), gcc-2.96.

Thanks,

Ronald

Did you copy /bin/insmod.old to the initrd that you are booting from?
Is /bin/insmod.old a static binary?

/bin/insmod.old is a symlink to the dynamically linked binary in
/sbin/insmod.old. The static one is in /{s,}bin/insmod.static.old.
Should I swap them around?
Also, I did recreate the initrd image (that should be enough, right?),
but still get the same error on bootup.

Thanks,

Ronald

Re: 2.4.21 doesn't boot: /bin/insmod.old: file not found

I am getting the same unexplained error message: Can't run
/bin/insmod.old, file doesn't exist, when trying to load jbd.o and
ext3.o. My system is running Redhat 9, and the error occurs with 2.4.21,
and 2.4.22-pre1

I have 2.4.21-rc7-ac1 booting fine. It seems I came across the same
error when first booting from that kernel, but I can't figure out what I
did to make it work.

This is a strange error so I'm not sure what info to post. Not being
able to boot and run on 2.4.21/22 is holding me up from important
projects, so everyone please help, or tell me what info I should send in
order to solve the problem.

initrd needs the static version of insmod.  Copy /sbin/insmod.static.old
to the ramdisk and rename it as /bin/insmod.old to suit the 2.5 modutils.

Re: 2.4.21 doesn't boot: /bin/insmod.old: file not found

[John Shillinglaw]

Aha, Thanks, 

Is there a howto page yet that tells all about how the old and new
module utilities work? I'm sure it's right under my nose...

BTW, after vowing not to, I solved the problem by simply making ext3
part of bzImage.

Now I got back to 2.5.73...

Thanks again,
Ian

Ah, right, insmod.static.old was indeed missing, I basically assumed
it'd copy that one in automatically (since it worked for 2.4.20), but
apparently, 2.4.20 just worked for no apparent reason while it shouldn't
have.

Adding insmod.static.old to the ramdisk image (add the line 'inst
/sbin/insmod.static.old "$MNTIMAGE/bin/insmod.old"' in /sbin/mkinitrd)
fixed the issue for me. Thanks for the pointer!

The modutils install doesn't save insmod.static (it should).  Assuming
you save the original 2.4 version as insmod.static.old, then the following
change to mkinitrd should correctly handle both 2.4 and 2.5 kernels.

I'd make that:

[ -x /sbin/insmod.old ] && inst /sbin/insmod.static.old "$MNTIMAGE/bin/insmod.old"

Just paranoia...
