Description of problem:
Some of the scsi drivers in this kernel package cannot be loaded.  
After upgrading from update 2 to update 3 of kernel-smp package, boot 
fails in a kernel panic when driver for the scsi controller fails to 
load.

So far this problem has been observed for 2 different scsi drivers, 
aic7xxx and mpt. 

Version-Release number of selected component (if applicable):
kernel-smp-2.4.21-20.EL 

How reproducible:
Always

Steps to Reproduce:
1.upgrade to latest kernel-smp rpm 
2.reboot


Actual Results:  System fails to boot -- panics after the attempt to 
load scsi driver from ramdisk fails with unresolved symbol errors

Expected Results:  System should still boot normally after kernel 
upgrade

Additional info:

The addon modules directory included earlier versions of the mpt 
driver for the fusion controller, and these versions are able to be 
loaded (I manually included those modules in a ramdisk and got the 
system to boot). Whatever went wrong in the build only affected the 
drivers in the main scsi driver tree.
