I had a similar problem with a SiI680 (and since lspci states that Silicon Image was formerly CMD Tech. I thought it might be related). In my case, I got lost interrupts and dma errors when I used both channels of the SiI680 simultaneously. I serialized both channels (kernel parameters ide2=serialize ide3=serialize) and the problems went away (I am not sure though how much of a performance impact it has).
Note for others: Using the ideX=serialize parameter simply causes the IDE driver to never allow simultaneous activity on the "serialized" channels. A small performance tradeoff in exchange for reliable operation. The drives can still seek independently and all that, just without any overlap in operation.
