    SubjectRe: [PATCH 2.6.24] mm: BadRAM support for broken memory

    That's how it's most often used, indeed. I do value the environmental
    aspect as well: the potential for memory manufacturers (say, for the
    $100 laptop) to ship out their broken memories at a low cost, thereby
    delivering more products for a given amount of toxic waste created in
    the chip etching process.

    > I would very much like to see this patch in mainline

    Many, many people want to. I've been asked about it a lot, but always
    lacked the time to figure out how.

    Actually it's broken memory that makes reports unreliable, not the patch :)

    After the right set of broken addresses has been applied, the whole system
    runs as reliably as any other system. And I hope people have the wits to
    mistrust a system for a while after they've plugged in broken DIMMs ;-)

    I doubt that'll be necessary, but yes, it'd be a way out. Thanks.
