qlogicfc attaches to both 2100 and 2200 ISPs. It seems you're then trying to load qla2xxx driver along with the 2300 and 2200 firmware loader modules. The pci_request_regions() call during 2200 probing fails.

Causing this cleanup badness.

Badari, is there some reason you are using qlogicfc? THe qla2xxx driver supports all QLogic ISP parts.

I'll look into this as well
