hrm. IIRC, the old-IDE code just sorta ignores this, and in the
original libata I followed old-IDE's habit of acking events with
write-to-dma-status-register(err | intr)
so what part of libata-core cares about this distinction? what is the
specific behavior from the original problem report that this solves?
