Basically I want to find out if we are getting and sense codes that we
are not handling. To that effect, andd the following line at the top of
the function rdac_check_sense()
--------
sdev_printk(KERN_ERR, sdev, "I/O returned with sense %02x/%02x/%02x",
                      sense_hdr->sense_key, sense_hdr->asc, sense_hdr->ascq);
---------

compile the module, run your tests and get me /var/log/messages.
