Description of problem:
After upgrading from FC1 to FC2 the USB Host Controller won't load
anymore causing an Oops.

The boot will continue after this but it will hang later on while
running kudzu, no message and the system is not dead (will react to
CTRL+ALT+DEL) but will not continue at all.

After logging in in single user mode and disabling kudzu a reboot will
continue past this point but will hang later on while bringing up the
network interfaces, again no message and the system is not dead.

Again in single user mode removed:

 alias usb-controller usb-uhci

from modprobe.conf and after that everything works fine.

Waiting until the system has booted completely and typing

 modprobe usb-uhci

in a console the system log shows that the usb stuuf loads correctly.

So it seems somehow to only happen while booting.

Version-Release number of selected component (if applicable):
kernel-2.6.5-1.358

How reproducible:
Always

Steps to Reproduce:
No need for steps, it happens at every boot.

Like I said in the Desciption above I can now actually boot by
disabling the usb stuff from loading. To reproduce the above behaviour
I only need to re-enable the alias line for the usb-controller in the
modprobe.conf.

Actual Results:  System hangs while either trying to run kudzu or
while trying to bring up the network interfaces (all of this worked in
FC1).
