RedHat 7.2 shipped with IDE disks running with DMA disabled. (I assumed that was a workaround for buggy hardware or a buggy driver.) That was ok with light loads which covered most usage patterns. I had a couple of hacks for measuring disk throughput that would generate lost interrupts every time. Lots of them. Turning on DMA solved the problem. -- These are my opinions, not necessarily my employer's.
