Are you using IDE in PIO mode? If so, the bug probably lies there. As I've said repeatedly when asked by IDE folk to test their PIO-based cache coherency fixes, I am unable to reproduce the bug, ergo I am unable to test the fix. (Some people, such as Jeff Garzik to name names, took that as me being entirely unreasonable and un-cooperative. But consider carefully - how can _anyone_ test something that they can't produce. I consider Jeff's comments extremely very childish in that respect.) Hence, as far as I'm aware, Linux on PIO-based IDE ARM hardware remains utterly *unsafe*.
