I experienced exactly the same problems when I was running 2.5 kernels for
the first time. I think the problem is that the module-init-tools are
installed in /usr/local/sbin instead of /sbin. In /sbin are still the ol
dmodutils. When you simply run depmod, you will run the module-init-tools,
but in the linux-makefile /sbin/depmod is called. You could simply copy the
modutils to *.old (depmod -> depmod.old), and make symlinks/copys of the
module-init-tools in /sbin (or just make sure make isntall installs them
there).

Did you have init-tools installed in /sbin before? This looks like the
message I saw from an early version of the package rather than the 2.4
version. In any case I think you either have to change the path to run the
correct module tool, or remake and install the tool in the compatible mode
which works with 2.4 or 2.5.

You'll need latest Rusty's modutils. You can download them 
at ftp://ftp.kernel.org/pub/linux/kernel/people/rusty/modules.

If you have a new enough version of modutils, and you rename these to
depmod.old modprobe.old etcetera, they are backwards-compatible...

I totally agree with this.

Ah, of course.  I followed the instructions that came with the
module-init-tools, and then just used "make modules_install".  
So much for following instructions.

I can only make the general observation that it would be helpful if:
- module-init-tools documentation pointed out this drawback of
installing to /usr/local/sbin
- module-init-tools documentation stated if it is or is not backward
compatible for the 2.4 kernels  (is it?)
- The kernel makefile used the module tools under /usr/local/sbin if
they exist.

(sigh)

Anyway, thanks again for the advice.

(2.5.65) Unresolved symbols in modules?

[Torrey Hoffman]

I'm trying 2.5 for the first time.  I am getting hundreds of unresolved
symbols in (all?) modules.  Note that:
- I have installed the module-init-tools. 
- "which depmod" as root says /usr/local/sbin/depmod
- depmod -V as root says "module-init-tools 0.9.10"

But make modules_install as root produces:

[lots of mkdir -p /lib/modules/2.5.65/kernel/...; cp drivers/... .ko
/lib/modules/2.5.65/kernel/...]

and then:
if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.5.65; fi
depmod: *** Unresolved symbols in
/lib/modules/2.5.65/kernel/drivers/char/lp.ko
depmod:         parport_read
depmod:         parport_set_timeout
depmod:         parport_unregister_device
...
[lots and lots of unresolved symbols in lots of modules]

What am I doing wrong?  What web page or kernel documentation should I
be reading?

Thanks
