KernelModuleBlacklisting
Disable automatic loading of kernel driver modules in etch.*
Warnings:
Do not use /etc/modprobe.d/blacklist.conf as, as can be seen in the comment of the header: naming modules there ...does not affect autoloading of modules by the kernel.
(Re)move /etc/modprobe.conf, if present, as it supersedes anything in /etc/modprobe.d/* (unless you add include /etc/modprobe.d).
The modules listed in /etc/initramfs-tools/modules aren't subject to blacklists so comment it first.
Howto:
Create a file '/etc/modprobe.d/<modulename>.conf' containing 'blacklist <modulename>'.
Run 'depmod -ae' as root
Recreate your initrd with 'update-initramfs -u'
Examples:
root@host:/etc/modprobe.d# ls -altr total 72 -rw-r--r-- 1 root root 363 Sep 24 19:57 pnp-hotplug -rw-r--r-- 1 root root 284 Sep 24 19:57 display_class drwxr-xr-x 2 root root 16 Oct 28 21:38 arch lrwxrwxrwx 1 root root 9 Oct 28 21:38 arch-aliases -> arch/i386 -rw-r--r-- 1 root root 1405 Oct 29 09:46 blacklist.conf -rw-r--r-- 1 root root 18 Oct 29 13:34 eth1394.conf -rw-r--r-- 1 root root 15 Oct 29 14:49 irda.conf -rw-r--r-- 1 root root 20 Oct 29 16:10 irtty_sir.conf -rw-r--r-- 1 root root 18 Oct 29 16:10 sir_dev.conf -rw-r--r-- 1 root root 19 Oct 29 16:10 nsc_ircc.conf -rw-r--r-- 1 root root 4360 Oct 29 16:21 aliases drwxr-xr-x 3 root root 4096 Oct 29 16:24 . -rw-r--r-- 1 root root 15 Oct 29 16:24 ipv6.conf drwxr-xr-x 47 root root 12288 Oct 29 16:25 .. root@host:/etc/modprobe.d# cat eth1394.conf irda.conf irtty_sir.conf sir_dev.conf nsc_ircc.conf ipv6.conf blacklist eth1394 blacklist irda blacklist irtty_sir blacklist sir_dev blacklist nsc_ircc blacklist ipv6
Addendum: Sometimes you've got to disable more modules to get the one you want: irda is such an example. In the above, irtty_sir, sir_dev and nsc_ircc all had to be disabled in order to disable irda. If you suspect something like that, run lsmod and find the modules that are using the one you want to disable.
Thanks to xingu and liable on irc #debian.
And thanks to -- ?BrendaButler for the suggestion - Should blacklisting be moved to another page? It's not part of udev.
