I would like to prevent ehci_hcd from loading at boot. Doing a modprobe
-r will remove the module, but it re-appers when rebooted. I could put
the command in rc.local, but I would rather not. I have tried the
following things, but it always gets loaded at boot:

Added "blacklist ehci_hcd" /etc/modprobe.d/blacklist
Tried "alias ehci_hcd off" to modprobe.conf
Tried "inistall ehci_hcd /bin/true" to modprobe.conf
I'm seems to be getting loaded with the initrd.img file. I see the
module directories when I mount the image to loop. I tried creating a
new initrd.img, but I havn't been able get the ehci_hcd module to not
show up in the newly created initrd.

Any suggestions?

It would help if we knew what version of the OS you're running.
Assuming something like RHEL 5.6, then you should remove what you did
before. Next you should add "blacklist ehci_hcd" to the end of the
/etc/modprobe.d/blacklist" file. Then remove the module from the
running system via:

# modprobe -r ehci_hcd

Finally, you need to rebuild the initrd image. This is usually done by:

# cd /boot
# mkinitrd -fv initrd-`uname -r`.img `uname -r`

Reboot and that should do it.

Sorry, meant to give RH version of 5.6. I had done the steps you
outlined above and the initrd created still loads the ehci module.
Removing the module and then doing a lsmod comfirms that it is unloaded.
Created the initrd again using the verbose switch as you suggested and
I see:

Looking for deps of module ehci-hcd
Using modules:
/lib/modules/2.6.18-238.12.1.el5/kernel/drivers/usb/host/ehci-hcd.ko
(among others)
copy from
`/lib/modules/2.6.18-238.12.1.el5/kernel/drivers/usb/host/ehci-hcd.ko'
[elf32-i386] to `/tmp/initrd.wb7347/lib/ehci-hcd.ko' [elf32-i386]
Adding module ehci-hcd

I did a strace as well, but I can seem to see why it continues to load
the module in the new initrd. I even tried using "blacklist ehci-hcd"
(instead of blacklist ehci_hcd) in all the /etc/modprobe.d/ blacklist
files and no change.
