Description of problem:
System will fails to boot when / is on iSCSI target. See full console log below.

Version-Release number of selected component (if applicable):
mkinitrd-5.1.19.6-65.el5

How reproducible:
1/1

Steps to Reproduce:
1. Start install of KVM virtual guest with latest 5.6 tree.
2. Attach iSCSI disk.
3. Place / on the iSCSI disk and /boot and swap on the local disk
4. Finish the install (I've selected all package groups in the UI)

Actual results:
System fails to boot.

Expected results:
System will boot.
