How about 2.4.22? Could it be that .21 doesn't yet fully support
the A7N8X's chipsets?
I have these set to "y" in my A7V133
CONFIG_BLK_DEV_IDE_MODES=y

YODA: Code! Yes. A programmer's strength flows from code
maintainability. But beware of Perl. Terse syntax... more
than one way to do it...default variables. The dark side of code
maintainability are they. Easily they flow, quick to join you
when code you write. If once you start down the dark path,
forever will it dominate your destiny, consume you it will.
