We've fixed a similar problem in RHEL5.3. What is the exact kernel version that panics? (In reply to comment #2) > We've fixed a similar problem in RHEL5.3. What is the exact kernel version that > panics? This is from kicking off an install from anaconda.

Description of problem: When zFCP loads (ananconda or live system) the kernel panics. I can reproduce this on two of my zFCP enabled guests, and my guests only.
