[SOLVED] Blacklist kernel module (stop autoloading) ?

Vilius · 08-29-2010, 06:21 PM

Hello,

Running Debian lenny.
I want Debian to stop from loading certain kernel module at startup. For now I tried adding "blacklist my_module" line in /etc/modprobe.d/blacklist file with no luck. Also I tried to add line above into some new file in /etc/modprobe.d directory - not working.

How do I blacklist kernel module in Debian lenny ?

thanks
Vilius

It's been a while since I've used Debian, but adding the line "blacklist device-driver" in /etc/modprobe.d/blacklist should do the trick. What is it your trying to prevent from loading? Are you sure it's a kernel module? does it show in lsmod?

Yes I'm sure.
It shows in lsmod.
This is upper coment of Debian /etc/modprobe.d/blacklist:

Quote:

# This file lists modules which will not be loaded as the result of
# alias expansion, with the purpose of preventing the hotplug subsystem
# to load them. It does not affect autoloading of modules by the kernel.
# This file is provided by the udev package.

So looks like it does not affect autoloading of kernel modules ?
(I checked another system and /etc/modprobe.d/blacklist works in redhat)

/etc/modprobe.d/blacklist.conf should work on Lenny.

You can also add it in the grub menu.lst.
