In some situation you may want to avoid loading a Linux driver module automatically . For example:
[a] You would like to use proprietary device driver (I'm against any sort of proprietary drivers) and not inbuilt (reverse engineer) kernel driver.
[b] If your server system connected without a diskette / floppy drive; kernel will try to load floppy driver - disable floppy driver or module.
[c] In some cases buggy driver causes kernel BUG on load so you just want to avoid the problem.
The Linux kernel get module information from /etc/modprobe.conf file and /etc/modprobe.d/* file(s).
If you are using CentOS/Redhat/RHEL/Fedora Linux...
Just open your /etc/modprobe.conf file and turn of auto loading using following syntax:
alias driver-name off
If you are using Debian / Ubuntu Linux...
open /etc/modprobe.d/blacklist file and add drivername using following syntax:
Reboot your box and use lsmod command to show the status of modules in the Linux Kernel.
