Then the newer driver will not help you.  I can reproduce this problem
here as well, and it appears that the data fifo on the aic7880 gets fauled
up when the target decides to disconnect with just the right amount of
data sitting in the fifo.  I'm still working the issue, but no guarantee
of when I'll have a solution.  This seems to only occur with Rev B. aic7880
silicon.
