[ Snipped possibility list ]

Another that should be noted, there is a known problem with some aic7xxx
chipsets and their BIOS in relation to the SCSI CAM Plug and Play capabilities.
Check your Adaptec BIOS and try changing the setting on this option and see if
the problem goes away (most people have to turn it off, while I've heard of a
few that had to have it on).
