Description of problem:
There is a PC with the ITE8212 raid controller,
to which the cd-rom is attached.
FC6 installed and worked without any problems
on this PC.
Trying to install F7 locks up the machine when
it is trying to load the pata_it821x driver.
We disabled the controller in bios setup to
install F7 anyway. Since the cdrom became disabled,
we booted from flash and did a network install.
After install, the problem didn't disappear.
The machine locks up on "Starting udev".
The only way to use F7 on this machine was to
add the pata_it821x to /etc/modprobe.d/blacklist
and live without a cdrom.

Version-Release number of selected component (if applicable):
kernel-2.6.21-1.3228.fc7

How reproducible:
Always

Steps to Reproduce:
1. Get the PC with the ITE8212 raid controller first.
2. Start the F7 installation
3. See the machine locked up when trying to load the driver
  
Actual results:
F7 installation freezes on start; F7 freezes on startup.

Expected results:
F7 installs; F7 boots; F7 works

Additional info:
The noraid option doesn't make any difference.
Actually, loading the pata_821x itself doesn't
lock up the machine, but loading sr_mod after it -
does. Still I think the problem is in the it821x
driver, but this is just a guess.
I'll attach the lspci and dmesg outputs.
The dmesg output is from the unupdated F7 kernel,
but the update released to that time, does not
solve the problem.
