It seems you're then trying to load qla2xxx driver along with the 2300 and 2200 firmware loader modules.

Badari, is there some reason you are using qlogicfc? THe qla2xxx driver supports all QLogic ISP parts. > Andrew, this driver should be converted to use the kthread API - using > kill_proc() from within a driver to terminate a kernel thread is kinda > gross. I'll look into this as well Thanks, Andrew Vasquez
