    At boot time, on a completely patched FC1 with kudzu off, error messages
    appear concerning mptbase and mptscsih. I didn't notice any of these
    messages before I ran a yum update to grab all the patches.

    The modules.conf contains 2 relevant lines:
            alias scsi_hostadapter 3w-xxxx
            alias scsi_hostadapter1 mptscsih

    This box has a 2 channel SCSI on the main board that currently has nothing
    connected to either channel. The 3Ware Escalade has all the drives connected
    to it. The Box's BIOS (ASUS PR-DLS533) has the SCSI BIOS turned off, and yet
    something has located the hardware anyway.

    After the 3WARE drivers are loaded, it attempts to load mptbase and fails
    once per channel on ioc0 and ioc1 bringup.

    Then I get a slew of :
    /lib/mptscsih.o unresolved symbol mpt_blah_blah_blah
    and finally:
    ERROR /bin/insmod exited abnormally.

    I've tried commenting out the mptscsih line in the modules.conf and also
    tried alias scsi_hostadapter1 off but neither worked.

    I'm not sure what builds the list of things that insmod is going to attempt
    to load. What's the correct way to tell the O/S not to attempt to load
    mptbase & mptscsih ? If I'm reading what man modules.conf says, then "off"
    is supposed to do it, but it doesn't.

    If in the future we do need to use the SCSI channels, how do I put things
    back?
