I've got a 2940UW I've been using for 2 weeks now. Haven't had any problems
with it at all. 

This is with 3 scsi drives and cdrom hanging off of it. I run all the
standard accounting plus all my daily stuff (sup, mail, etc) so I know the
disks get a good pounding during various portions of the day. This
is with both the older ahc driver and the newer one Charles just committed.
