I have always been using AUTO_EOI_1, but _not_ AUTO_EOI_2, and
it has always worked very well.
The comment in LINT about AUTO_EOI_2 sounds pretty suspicous,
so I never even tried it: "it works for some clones and some
integrated versions." That sounds to me like "it works on a
very limited set of hardware (and if you're lucky)."
AUTO_EOI_1 seems to be fine, though.

Oliver
