scsi tape drive troubles

I'm trying to make a scsi tape drive (conner CTD8000RS) work with my 7.3
(Ultra1) setup.  The Ultra1 has two scsi controllers recognized by the
kernel as a Sparc ESP100A-FAST, and a Sparc ESP366-HME, respectively.

The first controller is the one I'm concerned with here, which is known to
the kernel as "esp0".  On this controller are first two 4g hard drives
(sda and sdb) and the chain ends with the tape drive in question.

I have tried various things with the drive (including getting it swapped
for another of same type), but have not yet gotten the following problem
to go away.

Essentially, the two hard disks work fine but in combination with the tape
drive the scsi bus resets itself following a timeout (apparently in
negotiating the protocol with the first hard drive ??).  Below is the
relevant printout from dmesg (I've annotated the relevant lines with ">>>").

Can anyone tell me what may be going on here?  I'm starting to suspect the
drive just isn't compatible.... but I thought i'd give the "community" a
try....  any thoughts?
