Before we proceed further, could you retrieve the latest firmware
release for 24xx type HBAs:

You are loading some stale firmware that's left over on the card --
I'm not even sure what 4.00.70 is, as the latest release firmware is
4.00.27.  You can retrieve the image here:

	ftp://ftp.qlogic.com/outgoing/linux/firmware/ql2400_fw.bin

Let's start there... before we move on to this:
