Description of problem:

Testing FC performance on 2 system w/ qlogic luns
on both perf3.lab x86_64 (amd64) and bigbaddell2.lab x64_64 (em64t)

Luns which are visable to RHEL4 GA, U1 and U2 are no longer visible in U3.
on Qlogic   qla2xxx 

Same beta kernel ran fine with Emulex driver on x86_64 (em64t) perf4.lab
 

Version-Release number of selected component (if applicable):
 2.6.9-24.ELsmp

How reproducible:
Always

Steps to Reproduce:
1. install RHEL4 U3
2. attempt to mount or 
3.
  

Actual Results:  lsmod output

Expected Results:  
Should have seen the devices and fdisk, mkfs or mount should all work.
