So you haven't been testing what you think you're testing... Try booting your pata_cs5536 kernel with libata.dma=0 I also suggest you try a kernel with pata_amd compiled in instead of pata_cs5536. Slight timings aside there shouldn't be any functional difference between the way the two drivers configure things. But let us know how that goes. And include the diff of the relevant portion of the boot logs. Finally - which drive is it? -- Martin K. Petersen Oracle Linux Engineering
