What do you have on the bus besides the Empire?  I have heard from some
that newer Quantum drives will not talk at 10MB/s reliably with the
aic7xxx based cards.  This has not been my experience with my Empire 2100S.
You could try setting the Sync negotiation rate down to 8MB/s to see if
this helps you out.  Have you ruled out a VL-DMA problem?  Are you using 
active terminators?

If you have other things on the bus, can you target one of them as the
cause of the timeouts?
