[gentoo-user] can't unload modules

[gentoo-user] can't unload modules

[maxim wexler]

Hello everyone,

The ATI FAQ recommends compiling module unloading into
the kernel, which I did.

Then I tried modprobing the various requisite modules
to see what would work, fglrx, radeon, nvidia-agp etc.

But I found I couldn't rmmod anything; got FATAL,
Module unloading unavailable(something like that).

Does that advanced feature under module unloading need
to be checked as well? I thought I'd check with the
list about it. FAQ doesn't say.

Try using 'modprobe -rnv <module>' and see what errors you get.

Sounds like you don't have  CONFIG_MODULE_UNLOAD set (it's under
loadable module support in menuconfig)

Module unloading support is optional.  You want to enable it in your kernel config.

Maxim:

Try this command `cat /usr/src/linux/.config | grep CONFIG_MODULE_UNLOAD`. 
On my machine (which has module unloading compiled into the kernel) I see 
CONFIG_MODULE_UNLOAD=y

It would appear that it is not. Double check with my cat grep command and 
perhaps recompile your kernel.

Sounds like a forgotten "make mrproper" or "make clean" before a full 
build?

I'm sure the kernel isn't making this stuff up. :D

I knew it was there having just added it to the
.config yesterday after reading the ATI FAQ. Saved it,
then ran make modules_install. Did I forget something?

Aren't they for 2.4.x kernels? I'm using a 2.6.11.

You need to rebuild the kernel proper - it's responsible for loading
and unloading modules. Rebuilding just the modules won't help you.

And no, those make commands aren't just for 2.4 kernels - they work
with 2.6 kernels as well.

Run a make clean on the kernel source tree and then a make && make 
modules_install and see what happens. Perhaps that will solve it.

yes you forgot to make the kernel and forgot to install the kernel and
reboot.

the functionality for unloading modules does not itself reside in a
module!

make mrproper wipes .config, so be careful ;)

ps to see the .config for the running kernel you can:

zless /proc/config.gz

(although that too has to be compiled into the kernel - I recommend you
do it as standard, although it adds a little bit of size to the kernel.
It is very convenient if you accidentally blitz your .config file, which
you will  do if you use "make mrproper" without backing up)

Didn't forget. Those are obvious steps and not worth mentioning.

Everything is worth mentioning when something goes wrong. Sometimes the
problem with your cable TV reception really *is* that the power is
unplugged, after all.

That said, do you also have KMOD (Automatic kernel module loading) set?
I can't think of anything else that might have any affect on this,
unless the problem is with the specific modules that you're trying to
load/unload.

<crow_eaten> You are right. I had neglected that thing
called 'make'. </crow_eaten>
