It is very important when reporting problems. It sounds like you're trying to install an older version of FreeBSD, perhaps 2.2.1R? There were known bugs with the driver for the 2940 (ahc) in that version. Try installing 2.2.2R. Other things that could be causing problems are improper termination or bad cables. I've had problems installing 2.2.2R on a 2940UW at work because neither the internal DAT drive (HP C1599) or CD-ROM (Plextor 12-plex) would properly terminate the SCSI bus. I tried many different cables, but only an inline active terminator would solve the problem. The wide drive seemed to properly terminate the wide bus, probably because it was using active termination. Note that I was getting the same exact error messages you are describing. As a work around (until I could get my hands on an inline active terminator), I enabled Low byte termination in SCSI Select Utilities. I know this seems wrong, but it did work.
