That's a significant improvement, eh? :-)

What else is (still) on the bus with the IBM after removing the DAT?
If there is a CD, move that onto the 2906 bus and see if that makes
a difference.

Correct; if you must use the QLogic with both HDDs and CD/DAT on the
same cable, we recommend switching to the "feral" ISP driver, found
at:

It is *much* better at handling tricky termination issues, along with
the connect/disconnect situations.
