Just to add my 5 cents to this topic: I had similar READ_DMA_TIMEOUT problems with a Promise Ultra100 controller with 2 PATA disks that caused various problems including memory corruption under heavy use. As soon as I replaced the controller with a cheap VIA 6421 controller all problems went away. One strange thing was that when only 1 PATA disk is attached there are no (obvious) problems. The problems start to appear only when more disks are attached to the controller.
