Description of problem:

systems Crash when plugging Qlogic QLA2342 - 133MHz PCI-X to 2Gb FC, Dual Channel  
Card into Qlogic 5500 Fiber Switch


Version-Release number of selected component (if applicable):


How reproducible:

Happens on all four nodes to the cluster. When unplugged from Fiber switch, systems do not crash. 


Steps to Reproduce:
1. Plug wire from Qlogic Card to Qlogic Fiber switch
2. Power on Machine and boots starts
3. Kernel panics (only have partial since there is no buffer to ilo)
  
Actual results:

Kernel Panics: This is what I have captured

Expected results:

Systems should boot normally and see created storage presented to nodes. Also unplugged storage and still machine crashes


Additional info:

When installing RHEL53 from PXE, saw same behavior. Unplugged cables and OS installed fine. Then tried installing RHEL52 with fiber cables plugged in and no  
problems was observed.
