scsi errors

[Galen Johnson]

Greetings...

I'm having some issues with the aic7xxx driver (best I can tell it isn't 
device issue).  I have set up a poor man's jukebox of 14 DVDs.  They are 
attached to two individual Adaptec 2940U/W host controllers.  I am using 
this to copy a LOT of data over to one of my NAS setups.  This is 
connected to a Centronics connector on the towers (from 68 pin).  The 
problem I am seeing is that it is continually spitting out the following 
(randomly distributed across the scsi id's).

I know there are several boot time options I can give to the kernel. 
Can anyone suggest anything for me to try?  This is a bit above my 
current experience.  I'm running this with Slackware 9.0 and the 2.4.20 
kernel.  I experience the exact same problem under Redhat 9.  Some folks 
have suggested that I try BSD but I don't believe it to be OS related 
(not anymore).

Any insight would be greatly appreciated.
