    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*.
