Are you SURE it's not a cabling issue? I've had 2940U2w cards act strangely
both under Linux and NT when there were problems with cables or terminators.
I've gotten into the habit of using SCA drive cages and keeping the LVD
cable lengths to a minimum (just between the cage and the controller).
Yes, that is what I thought too. If slowing the bus down causes the
problems to disappear, it's almost certainly a cabling or termination issue.

If you can afford it and this is for real work, you may want to
consider something like a Network Appliance Filer. It will be
a lot more robust and quite a bit faster than rolling your own
array. The downside is they are quite expensive. I believe the
folks at Raidzone make a "poor man's"
I haven't had very good experiences with the Adaptec cards either.
If you can take the performance hit, the Mylex ExtremeRAID cards
come in a 3-channel variety. You could then split your array
into 3 chunks of 3-4 disks each and use hardware RAID instead of
the software raidtools.
