Did you make sure all your tools are up to date for the kernel you're building?
 (read the README file for proper versions of tools that need to be installed
to build the kernel.  MY guess is your modutils are too old, or your compiler
is one of the buggy ones..)

I've seen that before,  it's because you have an "alias scsi-hostadapter
aic7xx" in your /etc/modules.conf.  The problem is even removing that lines
doesn't always solve the issue, as mkinitrd see's that the aic7xx module is
currently loaded and sees that it's necessary, thus tries to force the initial
ramdisk to have it in it..

IF you compiled in your scsi module and fs module for your root filesystem,
then and initial ramdisk isn't usualy necessary. (only really used if your boot
adapter, or boot filesystem is built as a module)

Like I said above if you built in all the things you need to boot, the initial
ramdisk is probably not required. (I don't run one and I uses SCSI/EXT3 for
bootup, as my SCSI module and ext3 drivers are built into my kernel,  just
about everything else I made modular...)
