Sounds like it could be a termination problem. If the tape is the only device on the chain make sure the controller is terminated, and the tape drive is terminated. Make sure the cables are good quality, and short - In the bios on the 2940 try setting it to 'Allow Sync. Negotiation: No'. See if the Tape driver has a jumper for 'Termination Power', and see whether it's on or off (I think it should be Off for such a small bus, but try it 'On' as well)... We have had very similar messages here when our Termination has been off...
