Can a termination problem cause total kernel hangs?

Right now, at least two of us on -questions are experiencing problems with
total lockups (no pings) when in X, usually when using Netscape (in my
case) or in heavy concurrent disk accesses (in Malte's case) on SCSI
systems with a number of SCSI devices. (4 to 7). 

Malte has had success in reducing the hangs by changing the termination,
and I'm wondering if the sorts of hangs we're looking at could be caused
by termination problems.

Both of us have Adaptec 2940UWs.

Any ideas or suggestions?  I had thought that a SCSI hung kernel would at
least return pings?
