I've been working through a set of DMA problems. The PIO/DMA switching timing out is fixed and has been for a while. I've very recently fixed a race where we could get a command issued while resetting an interface.
With 2.4.x the reports I have make me think there are more races in ide-scsi left. With 2.5.x its completely broken. Someone rewrote the abort/reset handling, some other people rewrote the scsi core and the result needs significant work yet
