I can't explain why adding a second SCSI disk could cause this problem, unless it's a "green" disk that has spun down. Most likely, there is a tagged command queue problem. Depending on which version of kernel you are running, you may need to enable *at least* as many queues as you have drives. On the other hand, it may be a bad queue interaction if they are enabled by default (I don't have a 2940 -- I run NCR controllers), in which case you might need to disable them. Basically: toggle the things and see if it helps. If you still have problems, you'll need to contact the driver maintainer.
