| Post subject: | How to avoid loading unneeded kernel modules? |
I just checked my new KM box, and there are 87 kernel modules loaded. About have of them are unused. What's the best way to get rid of all of the extraneous kernel modules that are being loaded? |

This is very tricky. You can back-up /etc/modules and replace it with an empty file. Then reboot and hope for the best. If something is not working you'll have to figure out what driver is required and put it back into /etc/modules. Be warned, you may have trouble with USB keyboards, mice, etc without forcing some drivers to load. |

Be warned, you may have trouble with USB keyboards, mice, etc without forcing some drivers to load. It seems to be pretty obvious which drivers aren't needed. I don't even have a BTTV board or an IVTV board or a CX8800 card, yet there are drivers loaded for all of them. I don't use IEEE1394 for anything. Why would I need those drivers? You can look at lsmod and see that half the drivers have 0 usage. I would think that doing lsmod snapshots during various different modes of operation (recording, playback, music, video, mytharchive, etc.) would give a pretty clear picture of which drivers are actually needed. |
