Starting iscsid - generates unknown symbol in module

Attempting to upgrade a server installation to 5.9 (previously 5.3). Following base installation, starting the iscsid service generates a number of warning/fatal messages listed below. Could anyone enlighten me about the messages? Are they a problem or not? Why is the symbol not in the module? Is there a work around?

dmesg lists registered transports for cxgb3i, tcp, and be2iscsi (not bnx2i, or ib_iser)

Thanks for any replies.
