    Well in that case perhaps something else broke. I've seen no such reports
    of recent regressions in the ramdisk driver.

    The two problems of which I am aware are:

    a) It loses its brains across umount. Seems that it's very rare that
    anyone actually cares about this, which is why it has not been fixed in
    well over a year.

    b) It loses data under heavy I/O loads. I _think_ this has been
    observed only on ppc64 and might be a cache writeback/invalidate thing.

    If there are new post-2.6.5 problems then I'm all ears.
