    SubjectRE: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)
    Date
    From
    I am hopeful that the sata_mv has this bug (I proved that the
    problem I was experiencing was due to the sata_mv driver
    with 3.75Gig or more of memory)...

    I am on vacation for a week or more ...or I'd tell you today
    if it did have this bug!

    Mmm.. I wonder how many other libata drivers have this exact same bug,
    whether noticed yet or not ?

    Cheers
