[WBEL-devel] Missing Kernel Modules

Discussion:

I have noticed something and I'm not quite sure why it's happening.

I have noticed that on a normal install, the WhiteBox Kernel is missing
some modules that should be installed based on the config file that is
installed in /boot.

Some modules that I have noticed that are for sure not there (but are
set to XXXXXXX=m in the config file) are:

tun
bridge
ftape
imm

I am sure there are others as well, but I haven't specifically checked.

This isn't a major problem for me, I can recompile the kernel by
installing the kernel-source, going /usr/src/linux-2.4 and doing:

1. make mrproper
2. copy the default config file down from /boot to .config
3. Edit the EXTRAVERSION= line (in the Makefile) to remove the custom
4. make oldconfig
5. make menuconfig (if I want to change any options ... like processors
type)
6. make dep
7. make bzImage
8. make modules
9. make modules_install
10. make install

But, my question is, why does the kernel installed not match the
/boot/config file installed?

I checked this with the original kernel (2.4.21-4EL) and 2.4.21-9.0.1.EL
... also with the smp kernels.

I will also check this on RHEL and post the results.

Thanks,
Johnny Hughes

This exact same behavior is present in RHEL AS 3 (Taroon). The specific
4 modules I listed in the original e-mail are set to XXXXXX=m in the
included /boot/config file and not installed on the system. Recompiling
the kernel with the /boot/config file as the .config file in kernel
source installed the modules correctly. So this is an upstream issue
... any ideas why it is happening?

I provide a lot of advice at http://linuxhelp.ca and I highly recommend
WhiteBox there, but lots of people might be weary of recompiling the
kernel...

I checked the same issue in RedHat 9 and FedoraCore 1 ... all the
modules that I looked for (that had XXXXXXX=m in the /boot/config file)
where present on the system...

Have you checked the kernel-unsupported-* rpm... The kernel-unsupported
rpm contains alot of the modules included in FC1 etc.. I have a couple
of machines where I needed to install the unsupported rpm to get things
like DV capture cards to run.

HTH.

Thanks Craig ... that was it. Now, what is really bad is .. I gave
exactly that same advise to someone else about a month ago concerning
kernel modules in RHEL ..... :) . I must be getting senile!

Glad to be of some help, I'll let you off on your memory lapse :) but
only because I'm guilty of it too..
