Out of curiosity, I'm resurrecting this old thread: how was the slow
storage problem resolved?  (I assume it was resolved because storage
speeds on Fedora 17 on my Pandaboard are nice and fast.)

I don't see Mark Salter's patches in the kernel, though.

Émeric Vigier mentioned (in a private email) that this may have been
resolved with this patch for PL310 erratum 769419:
  https://lkml.org/lkml/2011/12/7/393

Was this ^^ patch the final solution?  I *do* see this change in the
Fedora kernel sources.
