EmuTOS carefully follows the rules in the "Atari ACSI/DMA Integration Guide": 
on p.14, it explains what the driver needs to do to avoid the "DMA CHIP 
ANOMALY".  I suspect that the changes in 1.8.0 broke this, and the subsequent 
change fixed it again.  But until I can get a current version of Hatari to 
work, I have no way of testing this ...
