Uh, are there more than one Adaptec 2940's out there?  (Other than the 2940W
Fast/Wide appelation, that is)

I could have sworn I was using one (running on a 1 day old -current):

scipio# uname -a

All I know is that this sucker *screams* and I've had *no* problems whatsoever
that could be remotely considered disk-related ... certainly nothing like our
friend from Hong Kong is suffering through ...

(Two 2.1 Gb SCSI disks, a Pioneer DRM-640 6-CD jukebox changer, and an Exabyte
  EXB-8200 on the SCSI bus)
