Many unneeded kernel modules are loaded

+++ This bug was initially created as a clone of Bug #211780 +++ Description of problem: Using kernel-2.6.17-1.2293_FC6, not much overhead was loaded: video button battery ac lp parport_pc parport. But things changed using kernel-2.6.18-1.2798.fc6: button battery asus_acpi ac scb2_flash mtdcore cfi_probe chipreg map_funcs pcspkr sbs i2c_ec parport_pc lp parport i2c_piix4 i2c_core gen_probe serio_raw video Why do you believe I need this whole mess automatically loaded? I'm accepting video as there is a graphics controller and maybe the ACPI stuff even it doesn't make sense at a server, but the rest seems more than nonsens to me. And the box has neither parport nor for Linux usable i2c/SMBus or any Asus components. There even isn't a sound card or a beeper which could be used for pcspkr. Ha and ever seen a 1U rack server supporting any type of CFI-compliant flash chips? Version-Release number of selected component (if applicable): kernel-2.6.18-1.2798.fc6 How reproducible: Buy a HP ProLiant DL360 G3, G4, G4p or G5 and install Fedora Core 6. You'll get the same mess installing Red Hat Enterprise Linux 5 when ready and not fixed... Actual results: Many unneeded kernel modules are loaded. Expected results: Only kernel modules loaded which are really needed and not just every module standing or lying around and looking a bit pretty... ;-) Additional info: The following also looks strange to me (ehci, ohci and uhci at the same time?): ehci_hcd 35533 0 ohci_hcd 25181 0 uhci_hcd 27725 0
It looks like this is a case of a newer kernel providing updated drivers (modalias, new hardware support) that udev then loads automatically on boot. I don't really see what the bug is here - it's possible to tell the tools not to load these drivers, if you really want. Unless I'm missing something, this is not actually a "bug", more a feature that's resulting in some extra modules loaded.
