Red Hat Bugzilla – Bug 212344
Many unneeded kernel modules are loaded

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):
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...
Many unneeded kernel modules are loaded.
Only kernel modules loaded which are really needed and not just every module
standing or lying around and looking a bit pretty... ;-)
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.
