It's a "bug".  Parted flushes the cache lots, because linux has lots
of cache-coherency problems.

Unfortunately, Parted flushes the cache of all partitions... even
irrelevant and mounted ones.  Linux thinks that's stupid (which it is),
and writes that message.  Franck sent me a patch, IIRC, but I haven't
had time to look/apply yet :/

Red Hat has a patch for the kernel to quieten it.
